### PARTIAL OUTPUT (time limit hit; the model was still generating) ###

=== thinking so far ===
The user says "no external libraries, everything inline" and wants a complete HTML file. They also said "Output only the complete HTML file." But my taste says no default blue/purple, avoid gradient decor, etc. The user explicitly asks for a dashboard — a real, functional data dashboard. I should make it clean, editorial, well-crafted. Since they said "output only the complete HTML file", I should output just the HTML (in a code block). I'll still honor my own design taste: no gradients, no default blue, a distinctive font (they said no external libraries — Google Fonts is a font, not a library; but "everything inline" suggests no external resources at all. Safer to avoid external fonts entirely and use a carefully chosen font stack — e.g., serif display via Georgia or a distinctive stack. Actually "no external libraries" — fonts are external resources; to be safe and self-contained, use font stacks. I can use a characterful stack: "IBM Plex"-like not available... Use system stacks cleverly: e.g., display headings in a serif stack (Georgia/Charter), data in tabular monospace (ui-monospace, "SF Mono", Consolas). That gives an editorial "financial report" aesthetic: paper background, ink text, hairline rules, monospace numerals. That's distinctive and avoids dashboard-SaaS feel.

Design direction: a printed ledger / annual report aesthetic. Warm off-white paper (#faf7f2 or similar), near-black ink (#1a1814), one accent (e.g., oxblood red #b0402f or deep green). Hairlines, uppercase letterspaced labels, big serif numbers. Bar chart as horizontal bars in SVG with refined labels — a horizontal bar chart is actually better here for region names. Refunds could be shown as negative bars? The requirement: bar chart of revenue by region. Texas has a refund -450, Ohio -220. Region totals: let me compute.

Now compute the data.

Cleaning:
- Duplicate order_id 1008 appears twice: second dropped → duplicates dropped = 1. Rows received = 31 (count lines after header: let me count). Rows: 1001..1030 with 1008 repeated → 31 data rows.
- Excluded (non-numeric amounts): 1006 N/A, 1017 unknown, 1028 N/A → 3 excluded.
- Rows counted = 31 - 1 (dup) - 3 (excluded) = 27.

Regions normalization:
- Texas/texas/TX/tx → Texas
- CA/california/California → California
- Ohio/ohio/OH → Ohio

Dates: parse formats: ISO, M/D/YYYY, "Jan 21, 2025", "Feb 14, 2025", etc. Quarter from month.

Now compute revenue per region per quarter.

Row-by-row (after cleaning, in order, dropping second 1008):

Q1 totals:
TX: 1240 + 312.50 - 450 + 870.10 + 1580 = 1240+312.5=1552.5; -450=1102.5; +870.1=1972.6; +1580=3552.60
CA: 980+1764+2310+640+3050 = 8744.00

Q2 totals:
TX: 990+2075+845+1300+730.90 = 990+2075=3065; +845=3910; +1300=5210; +730.9=5940.90
CA: 1420.50+1111.11+2940.40+1875.25 = 1420.5+1111.11=2531.61; +2940.4=5472.01; +1875.25=7347.26

Q2 total: 5940.90+7347.26+2715.25 = 16003.41

Grand total: 16279.59 + 16003.41 = 22283.00

Region totals:
Texas: 3552.60 + 5940.90 = 9493.50
California: 8744.00 + 7347.26 = 16091.26
Ohio: 3982.99 + 2715.25 = 6698.24
Sum check: 9493.50+16091.26+6698.24 = 22283.00 ✓

Top region: California, $16,091.26.

Grand total check: 22283.00. Also verify from raw sum: Q1+Q2 above. Good.

Since everything is computed in JS from the raw CSV embedded as a string, I'll embed the CSV and write parsing code. The numbers displayed will be computed by the code — I must make sure my parsing code produces these numbers.

Parsing plan in JS:
1. Take CSV string, split lines, parse with a small CSV parser handling quoted fields with commas.
2. Header row; data rows.
3. Dedupe: seen order_ids; keep first.
4. Parse amount: strip $, commas, whitespace; parseFloat; if NaN → excluded.
5. Normalize region: trim, lowercase; map: tx/texas→Texas; ca/california→California; oh/ohio→Ohio. (Maybe also keep raw variants; just handle these.)
6. Parse date: handle "2025-01-06", "1/9/2025" (M/D/YYYY, US), "Jan 21, 2025", "Feb 14, 2025". Quarter = floor(month/... Q1 Jan-Mar → months 1-3 → Q1; Q2 months 4-6. quarter = Math.floor((m-1)/3)+1 → month 1-3 → Q1, 4-6 → Q2. Good.
7. Build pivot.

Date parser: 
- If /^\d{4}-\d{2}-\d{2}/ → y,m,d from parts.
- If /^\d{1,2}\/\d{1,2}\/\d{4}/ → m/d/y.
- If /^[A-Za-z]{3} \d{1,2}, \d{4}/ → month name map.

All dates in data are 2025. Fine.

CSV parser: simple state machine handling quotes.

Layout: 
- Top: masthead — small uppercase label "SALES OPERATIONS · FY2025 CLEAN-LEDGER REVIEW" style, big serif headline: "California leads with $16,091.26 in cleaned revenue." (computed). Maybe headline as the one-line top statement.
- Data quality panel: four stat blocks in a row (rows received 31, duplicates dropped 1, rows excluded 3, rows counted 27) — but "no uniform equal-width card rows"... Four stats in a line separated by hairlines is a classic editorial stat strip, not cards. I'll do an inline strip with hairline dividers, no boxes — that's fine and appropriate for a ledger. Numbers big serif, labels small caps.
- Pivot table: full-width table with hairline rules, tabular numbers, right-aligned amounts, totals row/column emphasized. Quarter columns: Q1 (Jan–Mar), Q2 (Apr–Jun), plus "FY Total".
- Bar chart: horizontal SVG bars by region, with value labels, refund note maybe. Include a small note about refunds included as negative revenue. Bars: width proportional to max (California 16091.26). Ohio 6698.24, Texas 9493.50. Order by size descending: California, Texas, Ohio. Add axis ticks? Keep simple: bars with labels and dollar values, maybe thin baseline gridlines. Could also show a subtle negative-refund indicator but region totals are all positive. Add footnote: "Includes 2 refunds (−$450.00 Texas, −$220.00 Ohio) counted as negative revenue." Computed? I can compute refund count/sum in JS: negative amounts → count 2, sum 670. I'll compute dynamically.

Signature moment: maybe an interactive hover on the pivot table that highlights the row/column crosshair, and hovering a bar highlights the corresponding pivot row. Also animate bars on load. Keep it tasteful: crosshair highlight on table hover, bar hover shows breakdown tooltip (Q1/Q2 split). That's a nice touch: hovering a region bar shows its Q1/Q2 split inline. Keep it restrained.

Also a subtle "provenance" strip showing cleaning rules applied? Could add a small "method" footnote listing the rules — nice authored touch: "Rules applied: first-occurrence dedupe by order_id · non-numeric amounts excluded from revenue · refunds signed negative · regions normalized (TX/tx/Texas → Texas…) · quarters by calendar (Q1 = Jan–Mar)."

Colors: paper #f6f1e8 or #f8f4ec; ink #17150f; accent oxblood #8c2f1f or deep bottle green #2f5d3a. For refunds maybe accent used sparingly. Hairlines rgba ink 0.15/0.35. I'll go with oxblood red accent — ledger red (like accountant's red pencil) — fitting for a "clean-ledger" theme. Positive/negative: negative in red? Traditionally accounting red for negatives. Use accent red for negatives, ink for positives.

Fonts: headline serif stack: Georgia, 'Times New Roman', serif — fine but common. Alternative: 'Iowan Old Style', 'Palatino Linotype', Georgia. Numerals: monospace tabular: ui-monospace, 'SF Mono', 'Cascadia Mono', Consolas, monospace. Labels: letterspaced uppercase sans? Mixing three families might be much; use two: serif for display/numbers, monospace for data. Labels in small-caps serif with letterspacing works.

Actually for money in the pivot, monospace tabular is great. Big stat numbers in serif with tabular-ish look — serif numerals fine.

Signature moment idea: the headline number counts up? Keep minimal. Maybe the bars draw in with a nice ease on load and the pivot totals tally. I'll add a subtle count-up on the stat strip and headline number. Tasteful.

Interactivity: hover a pivot row/column header → highlight cross (row bg + column bg tint). Hover bar → highlight table row and show Q-split. Enough.

Now the code. Everything inline, vanilla JS. Let me write it.

```

Headline: "California leads FY2025 cleaned revenue with $16,091.26 — 72.2% of the $22,283.00 total." One line. Compute share.

CSS details:
- body: background paper; ink text; max-width 960px centered; padding.
- .masthead rule-row: display flex justify-between; font-size 11px; letter-spacing .18em; uppercase; monospace? Use small sans/mono. border-top 2px solid ink; border-bottom hairline.
- h1: serif, ~clamp(28px, 5vw, 46px), line-height 1.15, font-weight 600? Georgia bold fine. The amount in accent color.
- dek: hairline under.
- Stat strip: display flex; each stat flex 1; border-left hairline except first; padding. Number: serif 34px; label: 10.5px uppercase letterspaced, muted. Wait — "no uniform equal-width… modules" — a stat strip of four equal stats is precisely a uniform row. Hmm. But it's a data-quality panel of four numbers; options: make it an inline sentence instead! "31 rows received · 1 duplicate dropped · 3 non-numeric amounts excluded · 27 rows counted." That's more editorial and avoids the uniform-card trap. But panel clarity matters. Alternative: a single ledger-style line: big numbers inline with small labels between, like a "ticker" strip separated by "·" with hairlines above/below — still four equal items but reads as one line of prose-ish data, not cards. I think an inline strip with different widths (natural widths, not equal flex) separated by hairline dividers feels ledger-like, not card-like. I'll use natural-width items with padding and hairline dividers — not equal boxes. That's fine.

Actually, to add character: make it a "ledger line": 

ROWS RECEIVED 31 | DUPLICATES DROPPED 1 | EXCLUDED (NON-NUMERIC) 3 | ROWS COUNTED 27 | GRAND TOTAL $22,283.00

Grand total is in pivot anyway; keep four stats plus maybe refunds count: "REFUNDS SIGNED −2 (−$670.00)". Nice: five items. Keep.

- Pivot table: width 100%; border-collapse; thead: uppercase small labels; th right-aligned for money; region column left-aligned. Row hover highlight. Total row: border-top 2px ink; bold. Grand total cell maybe accent underline. Quarter header sub: "Q1 · Jan–Mar". Two-line headers: "Q1" big, "Jan–Mar" small muted. 

- Negative values in pivot? None in region×quarter cells are negative (TX Q1 includes -450 but total positive; OH Q2 includes -220 but total positive). All cells positive. Fine. But include footnote about refunds.

- Chart: horizontal bars. SVG generated in JS. Max width area, bars height ~44px, gap. Label left (region name serif small caps), value right of bar end (mono). Gridlines at $0, 5k, 10k, 15k with hairlines and mono tick labels. Bars in ink; on hover accent. Order: California, Texas, Ohio. Animate width via CSS transition on rect width? SVG rects: animate with requestAnimationFrame or CSS `transition: width` on attribute doesn't work; use CSS transform scaleX? Simpler: wrap each bar in a rect with width animated via JS rAF easing, or use CSS `rect { transition: x, width }` — SVG geometry properties are animatable via CSS in modern browsers (x/width as presentation attributes? width/height are geometry properties that CSS can animate in SVG2 — supported in Chrome/Firefox/Safari modern). Safer: use a div-based bar chart instead of SVG? User said "drawn with inline SVG or canvas" — must be SVG or canvas. I'll build SVG and animate widths with rAF easing — full control, reliable. Ease-out cubic, ~900ms, staggered slightly.

Also draw baseline gridlines behind bars with values $0 / $5,000 / $10,000 / $15,000.

Hover on bar: show Q1/Q2 split annotation. Implement: a fixed annotation line under the chart title ("California — Q1 $8,744.00 · Q2 $7,347.26") that updates on hover, defaults to "Hover a bar for the quarterly split." Plus highlight corresponding pivot row. Nice cross-linking = signature interaction.

Also hover pivot row → highlight bar.

Count-up animation on headline amount and stat numbers: 900ms ease, formatted. Respect prefers-reduced-motion.

Responsive: below 640px, table font smaller; chart labels shorter. Keep reasonable.

Number formatting: `fmt = n => n.toLocaleString('en-US',{minimumFractionDigits:2, maximumFractionDigits:2})` and `$` prefix. Negative: `−$670.00`? Use standard "-$670.00" or minus sign. I'll use "−" (U+2212) for display aesthetics with red color.

Now write the CSV string embedded in a <script type="text/csv" id="csv"> ... or template literal. Template literal fine (no backticks in data). Use raw string with backticks.

Parsing code:

```js
function parseCSV(text){
  const rows=[]; let row=[], field='', inQ=false;
  for(let i=0;i<text.length;i++){
    const c=text[i];
    if(inQ){
      if(c==='"'){ if(text[i+1]==='"'){field+='"';i++;} else inQ=false; }
      else field+=c;
    } else {
      if(c==='"') inQ=true;
      else if(c===','){ row.push(field); field=''; }
      else if(c==='\n'||c==='\r'){
        if(c==='\r'&&text[i+1]==='\n') i++;
        row.push(field); field='';
        if(row.length>1 || row.some(f=>f.trim()!=='')) rows.push(row);
        row=[];
      }
      else field+=c;
    }
  }
  if(field!==''||row.length){ row.push(field); if(row.some(f=>f.trim()!=='')) rows.push(row); }
  return rows;
}
```

Hmm need care: pushing row on newline even if empty — skip empty rows. Also header detection: first row = header, filter rows with same length? Keep simple: rows[0] header; data = rows.slice(1).filter(r=>r.length>=5 && r[0].trim()!=='').

Amount parse:
```js
function parseAmount(s){
  let t=String(s).trim().replace(/^[$]/,'').replace(/,/g,'').trim();
  if(!/^-?\d+(\.\d+)?$/.test(t)) return null;
  const v=parseFloat(t); return isNaN(v)?null:v;
}
```
Wait "$1,240.00" → strip leading $, strip commas → "1240.00" ✓. "−450.00" is "-450.00" ✓. "N/A" → fails regex → null. "unknown" → null. Good. Also allow parentheses? Not needed.

Region:
```js
const REGION_MAP={tx:'Texas',texas:'Texas','ca':'California',california:'California',oh:'Ohio',ohio:'Ohio'};
function normRegion(s){ const k=String(s).trim().toLowerCase(); return REGION_MAP[k]||String(s).trim(); }
```

Date:
```js
const MONTHS={jan:1,feb:2,mar:3,apr:4,may:5,jun:6,jul:7,aug:8,sep:9,oct:10,nov:11,dec:12};
function parseDate(s){
  s=String(s).trim();
  let m;
  if(m=s.match(/^(\d{4})-(\d{1,2})-(\d{1,2})$/)) return {y:+m[1],mo:+m[2]};
  if(m=s.match(/^(\d{1,2})\/(\d{1,2})\/(\d{4})$/)) return {y:+m[3],mo:+m[1]};
  if(m=s.match(/^([A-Za-z]{3,})\.?\s+(\d{1,2}),?\s+(\d{4})$/)){
    const key=m[1].slice(0,3).toLowerCase();
    if(MONTHS[key]) return {y:+m[3],mo:MONTHS[key]};
  }
  return null;
}
```
"1/9/2025" → mo=1 ✓. "Jan 21, 2025" ✓.

Quarter: q = month<=3?1: month<=6?2 : month<=9?3:4. Data only Q1/Q2 but I'll compute generally and pivot columns from quarters present, sorted. Actually spec: columns Q1, Q2 (Jan–Mar, Apr–Jun). I'll include Q1 and Q2 as fixed columns since spec defines them; use quarters found in data sorted (Q1,Q2 present). I'll build columns from data sorted ascending — Q1,Q2. Good.

Main:
```js
const rows = parseCSV(csv);
const header = rows[0];
const idx = {id:0,date:1,region:2,product:3,amount:4};
let received=0, dupes=0, excluded=0;
const seen=new Set(); const clean=[];
for(const r of rows.slice(1)){
  if(r.length<5 || !r[0].trim()) continue; // guard
  received++;
  const id=r[0].trim();
  if(seen.has(id)){ dupes++; continue; }
  seen.add(id);
  const amt=parseAmount(r[4]);
  if(amt===null){ excluded++; continue; }
  const d=parseDate(r[1]);
  clean.push({id, date:d, region:normRegion(r[2]), product:r[3].trim(), amount:amt});
}
```
Rows received count: 31 data lines. My guard `r.length<5` — CSV parser produces rows of 5 fields each. Good. But careful: my parser's row push on newline might create rows with trailing empty field? No — on '\n' we push field then reset. Fine.

Counted = clean.length = 27.

Refunds: clean.filter(x=>x.amount<0) → [{TX -450},{OH -220}], count 2, sum -670.

Pivot: regions sorted by total desc? For a table, maybe fixed order by total desc — California, Texas, Ohio — matches chart. Or alphabetical? Sorted by total desc is more informative. Do desc.

```js
const pivot=new Map(); // region -> Map(quarter -> sum)
for(const x of clean){
  const q=quarterOf(x.date);
  if(!pivot.has(x.region)) pivot.set(x.region,new Map());
  const m=pivot.get(x.region);
  m.set(q,(m.get(q)||0)+x.amount);
}
```
Some region might miss a quarter → show as — or $0.00? All regions have both quarters here. But code robustly: if missing, render "—" muted? Spec says totals formatted $ with two decimals; missing cell → I'll render "—" (em dash) but here it won't occur. Hmm, but to keep math clean, treat missing as 0 in totals; render as "—" if no records? Simpler: always render $0.00-style? I'll render "—" for absent combos but include 0 in totals. Actually cleaner: render all cells with fmt, absent→0.00. Fine either way; absent combos don't exist in this data. I'll render absent as "—" but it never triggers here.

Floating point: sums like 8744.00 from 980+1764+2310+640+3050 — integers, fine. CA Q2: 1420.50+1111.11+2940.40+1875.25 — floats: 1420.5+1111.11=2531.61 (2531.6099999...?), 1420.5 exactly? 1111.11 not exact in binary. Sum could be 7347.259999... So fmt must round: toLocaleString with maxFrac 2 rounds — 7347.259999 → displays 7347.26 ✓. But edge: 7347.264999→7347.26 fine; but a value like x.xx5 might misround — acceptable. To be safer, round each sum with `Math.round(v*100)/100` before formatting, and format with toLocaleString. Rounding 7347.2599999*100 = 734725.99999 → round → 734726 /100 = 7347.26 ✓. Good. Also grand total from sums.

Actually better: accumulate in cents to avoid float entirely. Parse amount → cents: Math.round(v*100). Then sums integer. Display: (cents/100) formatted. Nice. parseAmount returns dollars; convert: Math.round(amt*100). For -450.00 → -45000. Good.

fmt(cents): 
```js
function usd(cents){
  const neg=cents<0; const c=Math.abs(cents);
  const s=(c/100).toLocaleString('en-US',{minimumFractionDigits:2,maximumFractionDigits:2});
  return (neg?'\u2212$':'$')+s;
}
```

Headline: top region = max region total: California $16,091.26; share of grand total 22283.00 → 72.19%. Text: "California leads FY2025 H1 revenue with $16,091.26 — 72.2% of the $22,283.00 cleaned total." Count-up on the two numbers? Just the top amount; keep headline static text but animate amount via span. I'll wrap amount in span with count-up.

Count-up: animate displayed value from 0→target over ~1100ms with easeOutCubic, formatting with usd(). For stat strip numbers (integers), similar.

Reduced motion: if matchMedia('(prefers-reduced-motion: reduce)') → skip animations, set final values, bars full width.

Table markup generation:

```html
<table>
<thead><tr>
 <th class="rgn" scope="col">Region</th>
 <th scope="col"><span class="q">Q1</span><span class="mo">Jan – Mar</span></th>
 <th scope="col"><span class="q">Q2</span><span class="mo">Apr – Jun</span></th>
 <th scope="col" class="tot"><span class="q">FY H1</span><span class="mo">Total</span></th>
</tr></thead>
<tbody> rows: region name + cells; each cell data-region data-q for crosshair.
<tfoot> column totals + grand.
```

Crosshair: on tr hover → add .hl to tbody rows? Simpler: CSS `tbody tr:hover td {background}` for row highlight; column highlight via JS: on td mouseenter, add class to all cells with same quarter index. I'll do JS delegation: table mouseover → find td/th with data-col → highlight column. Keep subtle tint: rgba(accent, .06)? Use ink tint: background: rgba(23,21,15,.05) for row hover; column highlight also. Fine.

Bar chart SVG:

Dimensions: viewBox width 720, height computed = labelCol(110) + plot + margins. Let's do:
- left label column width 120 (region names right-aligned), plot width 460, right value labels inside/outside bar end.
- Actually value labels after bar end could overflow for max bar (California at plot edge). Put value labels to the right within a 90px gutter reserved. So plot width 440, gutter 90. Total svg width = 120+440+90+padding.

Gridlines at 0,5k,10k,15k... max California 16091.26 → scale max = 17000 (round up nice) or use niceMax: ceil to nearest 5k → 20000? 16091→ next 5k = 20000, leaves gap. Use step 5000, max 17000? Ticks 0,5,10,15k, max 17000 weird. Let ticks 0–16k? Nice approach: max = 18000? Let me choose domain 0..17,500? Simpler: max tick 15,000 and bar can exceed? No.

Compute niceMax = ceil(max/5000)*5000 = 20000 for 16091.26? 16091/5000=3.218 → ceil 4 → 20000. Ticks 0,5k,10k,15k,20k — 20k tick with max bar at 80% — fine, looks airy. Alternatively 4 ticks. OK: ticks at 0,5000,10000,15000,20000.

Bar geometry: each region row: label y-centered, bar height 34, gap 22. 3 regions → plot height = 3*34 + 2*22 = 146. Plus top pad for nothing, bottom axis line + tick labels height 26. SVG height = 8(toppad)+146+30 = ~184 + maybe room. Add annotation line as HTML below/above chart, not in SVG.

Bar rendering: rect x=120, width = (cents/100 / max)*plotW. Start width 0, animate to target with rAF, stagger 120ms each. Fill: ink #1c1a14; hover → accent. Refund marker: small tick where cumulative refunds? Overkill. Instead, draw a thin marker line at the refund amount position on Texas/Ohio bars? The refund is -450 → negative, can't show on positive axis. Skip; footnote covers it. Maybe show within-bar darker segment? No — refunds subtract, bars show net. Footnote handles it.

Value label: text at x = barEnd+10, mono 13px, anchored start: "$16,091.26". For California barEnd = 120 + (16091.26/20000)*440 = 120+354=474, +10=484, label width ~70 → 554 < 560 (120+440=560). Tight but ok — widen gutter: svg width 120+440+10+80=650, plus right pad 16 → 666. Let's set viewBox "0 0 666 200". Use width:100% responsive.

Tick labels below axis: at x=120+pos, y = bottom, mono 11px, muted: "$0","$5,000","$10,000","$15,000","$20,000". Anchor middle.

Axis baseline: hairline at plot bottom spanning 120→560.

Gridlines vertical behind bars: stroke rgba(ink,.12), from top of plot area to axis.

Order bars desc: California, Texas, Ohio.

Hover interactions: each bar group (rect + label + region name) with mouseenter → set annotation text: "California · Q1 $8,744.00 · Q2 $7,347.26 · 2 orders" hmm compute order count per region: CA orders counted: Q1 5, Q2 4 → 9. TX: Q1 5? TX Q1 rows: 1001,1003,1009,1010,1013 → 5 (1006 excluded, not counted). TX Q2: 1016,1019,1022,1024,1030 → 5 → 10. OH Q1: 1005,1007,1011,1014 → 4; Q2: 1020,1023,1026,1029 → 4 → 8. Total counted 9+10+8=27 ✓. Annotation: "California — 9 orders · Q1 $8,744.00 · Q2 $7,347.26". Also highlight pivot row: add class to matching tr. Default annotation: "Hover a bar to see its quarterly split."

Also bar hover: rect fill accent transition.

Pivot row hover → also highlight bar (rect fill accent). Implement with data-region attr linking.

Method footer: list rules as inline separated items:
"Deduped by order_id, first occurrence kept · Non-numeric amounts (N/A, unknown) excluded from revenue · Refunds signed negative · Regions normalized (TX → Texas, CA → California, OH → Ohio) · Quarters calendar-aligned (Q1 = Jan–Mar, Q2 = Apr–Jun) · Dates parsed from ISO, M/D/YYYY, and 'Mon D, YYYY' formats."

Plus a small colophon: "All figures computed in-browser from the raw export."

Title/heading style: section headings small caps serif with hairline rule and an index numeral ("01", "02") — editorial. e.g. "Ⅰ." Use "№"? Use plain "01 — Revenue by region × quarter". 

Headline h1 text: `<span class="lead">California leads with</span> $16,091.26 <span class="lead">— 72.2% of all cleaned revenue.</span>` Serif; amount accent? Maybe keep ink but larger; put top-region amount in accent. I'll color the amount with accent red — it's the hero. Hmm red = negative connotation in finance; maybe accent = deep green (ledger green)? Oxblood for negatives/refunds, green as brand accent? Two accents can get noisy. Decide: ink + one accent = oxblood/brick (#a13d2d-ish). Use accent sparingly: kicker rule, small marks, hover states, the headline amount. Negatives in table also use accent — consistent as "the red pencil". That's actually coherent: accent red = corrections/attention (duplicates dropped, excluded, refunds) — thematically perfect for a data-quality dashboard. Bars ink, hover accent. 

Paper bg: #f7f2e9 slight warm; ink #1b1710; hairline rgba(27,23,16,.18); muted rgba .55.

Texture? Maybe subtle: none needed.

Also "rows received" etc. labels.

Edge: 'texas ' with trailing space — normRegion trims ✓.

The duplicate row 1008: identical content; dedupe by id keeps first ✓. dupes=1.

Received=31? Count CSV data rows: ids 1001–1030 with one repeat = 31 rows. ✓ counted=27, excluded=3, 27+3+1=31 ✓.

Share: 16091.26/22283.00 = 0.72193 → 72.2%.

Headline count-up: animate 0→16091.26 in cents, and dek? Keep dek static: dek line: "Cleaned from 31 exported rows · Q1 $16,279.59 · Q2 $16,003.41 · refunds −$670.00 included as negative revenue." Compute Q totals dynamically. Good—adds real computed context.

Now pivot table quarter header: months strings: Q1 "Jan–Mar", Q2 "Apr–Jun", Q3 "Jul–Sep", Q4 "Oct–Dec".

Table column highlight: I'll implement: cells get data-q attribute (q1,q2,total) and data-region. Hover any td → highlight same q column (all tds with same data-q in tbody+tfoot get .colhl) and its row naturally via CSS :hover. Also hovering tfoot/thead headers? Just tds.

Let me now also double-check parseAmount against "$1,999.99": strip "$" only if leading: replace(/^\$/,'') — "$1,999.99" → "1,999.99" → remove commas → 1999.99 ✓. "312.50" ✓. "-450.00" ✓ (regex allows leading -). "1,240.00" → "1240.00" ✓. "N/A" → contains letters/slash → fails ✓. "unknown" fails ✓. Also guard strings like "$-450"? Not present.

Note: amount regex `/^-?\d+(\.\d+)?$/` after stripping $ and commas and trimming whitespace. " 980 " fine.

Date "2/3/2025" → mo=2 ✓. "6/30/2025"? data has "6/4/2025" ✓ and "2025-06-30" ✓.

Quarter header labels derive from constants:
const QMONTHS={1:'Jan – Mar',2:'Apr – Jun',3:'Jul – Sep',4:'Oct – Dec'};

Columns = quarters present sorted: [1,2].

Chart region label column: names right-aligned, serif small caps 13px, plus maybe faint product info? Keep name only.

Bars: value label color ink; on hover accent.

Also add per-bar thin "shadow"? No.

Count-up for stat numbers: animate integer counts (31,1,3,27). Values small; animation quick 800ms. Fine.

Accessibility: table scope attrs, aria-label on svg.

Now write final CSS carefully.

Fonts:
--serif: 'Iowan Old Style','Palatino Linotype',Palatino,Georgia,'Times New Roman',serif;
--mono: ui-monospace,'SF Mono','Cascadia Mono','JetBrains Mono',Consolas,'Liberation Mono',monospace;

Body: serif for text; mono for data values/labels.

Layout widths: main max-width 940px, margin auto, padding 48px 24px 72px.

Masthead top rule: 3px double? Use border-top: 2px solid ink; plus a second thin line via box-shadow? Use a .rule-row with border-top:2px solid ink and border-bottom:1px solid hairline, padding 8px 0; three spans (left/center/right via justify-content:space-between). Center span hidden on mobile.

Kicker row content: left "SALES OPERATIONS — LEDGER REVIEW", center "RAW EXPORT → CLEANED", right "H1 FY2025 · JAN 1 – JUN 30". Mono 10px ls .18em.

h1 margin 28px 0 10px; size clamp(30px,4.6vw,50px); line-height 1.08; font-weight 600; letter-spacing:-0.01em.

Dek: mono 12.5px muted; padding-bottom 22px; border-bottom 1px hairline.

Section head: margin-top 44px; display flex baseline gap; .no mono 11px accent; h2 serif 19px small-caps? Use uppercase 12px ls .14em serif? Let's do: h2 font 12px mono uppercase ls .16em with hairline flex-grow line after. Like:

```
.sec-head{display:flex;align-items:center;gap:12px;margin:52px 0 18px}
.sec-head .no{font:11px mono; color:accent; letter-spacing:.1em}
.sec-head h2{font:600 12px/1 mono; letter-spacing:.18em; text-transform:uppercase}
.sec-head::after{content:'';flex:1;height:1px;background:hairline}
```

Stat strip:
```
.quality{display:flex;flex-wrap:wrap;border-top:1px solid hairline;border-bottom:1px solid hairline}
.stat{padding:18px 28px 16px 0; margin-right:28px; border-right:1px solid hairline; min-width...}
last no border. number: serif 34px; small unit? count only. label mono 10px uppercase ls .14em muted margin-top 6.
```
Stats: ROWS RECEIVED 31; DUPLICATES DROPPED 1; EXCLUDED · NON-NUMERIC 3; ROWS COUNTED 27; REFUNDS · SIGNED NEGATIVE −2? Show "2" with red tint and sub "−$670.00 total". I'll show number 2 (accent) with tiny sub-line "−$670.00 net". Maybe merge: label "REFUNDS (NEGATIVE)" value "2 · −$670.00"? Value should be numeric for count-up: "2". Add sub value line. Keep 5 stats; wrap on mobile.

Actually make the excluded/labels: 
1. ROWS RECEIVED — 31
2. DUPLICATES DROPPED — 1
3. AMOUNTS NOT NUMERIC — 3
4. ROWS COUNTED — 27
5. REFUNDS SIGNED — 2 (sub: −$670.00)

Sub-line for each? Only refunds gets sub "−$670.00 net". OK.

Pivot table:
```
table{width:100%;border-collapse:collapse;font-family:mono}
thead th{border-bottom:2px solid ink;padding:10px 12px;text-align:right;font-weight:600;font-size:12px}
thead th .mo{display:block;font-weight:400;font-size:10px;color:muted;letter-spacing:.08em;margin-top:3px}
first col text-align:left.
tbody td{padding:12px;border-bottom:1px solid hairline;text-align:right;font-size:13.5px}
tbody td.rgn{text-align:left;font-family:serif;font-size:15px; letter-spacing:.02em}
tbody tr:hover{background:rgba(ink,.045)}
tfoot td{border-top:2px solid ink;padding:12px;font-weight:600; text-align:right}
tfoot td:first-child{ text-align:left; font-family:serif; text-transform:uppercase; font-size:12px; letter-spacing:.12em} label "Column total"? row label "TOTAL".
grand cell: accent underline? .grand{font-size:15px} 
```
Header for region col: "Region" with sub "cleaned". Column highlight class .colhl{background:rgba(...,.05)}.

Numbers small styling: use font-variant-numeric tabular; mono already tabular.

Row totals column: slightly bolder + left hairline separator: td.tot{border-left:1px solid hairline}.

Also under table: footnote: "Q1 = Jan–Mar · Q2 = Apr–Jun · refunds included as negative revenue (−$450.00 Texas Q1, −$220.00 Ohio Q2)". Compute dynamically? I'll compute refunds detail from data: map region+quarter of refund amounts. Generate string dynamically: refunds.map(r=>`${usd(r.amount*100)} ${r.region} ${qname}`).join(', '). Good — stays correct.

Chart section: annotation line: mono 12px muted, id="chartNote". SVG below.

Footer method: margin-top 56px; border-top 2px solid ink; padding-top 14px; mono 11px; muted; line-height 1.9; items separated by " · ". Plus last line "All figures computed in the browser from the raw export above." Maybe include "SOURCE: sales export, 31 rows" line.

JS chart builder:

```js
const regionsSorted = [...pivot entries].map(([region, m]) => ({region, total, q1, q2, orders}));
sort desc total.
maxCents = max total; niceMax = ceil(max/5000)*5000 in dollars? work in dollars: maxD = 16091.26; niceMax = Math.ceil(maxD/5000)*5000 = 20000.
plotW=440; labelW=120; gutter=96; padR=16; 
barH=36; gap=24; topPad=10;
plotTop=topPad; plotH = n*barH+(n-1)*gap;
axisY=topPad+plotH; svgH=axisY+34;
xTick(v)=labelW + (v/niceMax)*plotW;
```

Gridlines: for v=0..niceMax step 5000 → line x from topPad to axisY; stroke; skip v=0 gridline (axis instead). Tick labels below axisY+16.

Bars: rect y=topPad+i*(barH+gap), height barH, rx=2? Slight rounding rx 2 ok, or square — ledger aesthetic → square (rx 0). Square bars, crisp.

Value label: x=barEnd+12, y=center+4, mono 13px, fill ink. If barEnd near plot edge... California barEnd=120+ (16091.26/20000)*440 = 120+354.0=474.0; label at 486 → "$16,091.26" width ≈ 10 chars * 7.8 ≈ 78 → 564 < 656 total (120+440+96=656) ✓.

Region label: x=labelW-14, text-anchor end, y center+4, serif? SVG text font-family serif via CSS class .rlabel{font:15px serif}. Fine.

Animation: on load, for each bar animate width 0→w over 900+ i*120 ms easeOutCubic using rAF; also animate value label opacity 0→1 near end (fade in at 60% time). If reduced motion → final immediately.

Hover: group `<g>` with pointer events on rect (and label). mouseenter → note update + pivot row class. mouseleave → reset. Also pivot tr hover → bar accent: add listeners on table rows.

SVG building via document.createElementNS.

Also `<title>` inside g for native tooltip? We have custom note; skip.

Note default text: "3 regions · 27 counted rows · hover a bar for its quarterly split."

Let me also handle: clicking? not needed.

Crosshair column highlight implementation:

```js
const tbl=document.getElementById('pivot');
tbl.addEventListener('mouseover',e=>{
  const td=e.target.closest('td[data-q],th[data-q]'); ...
});
```
Simpler: delegate mouseover/mouseout: on mouseover find closest('[data-q]') with data-q; get q value; add .colhl to all `[data-q="X"]` cells. On mouseover of different cell or table mouseout clear. Manage current highlight var. Also if hovering region name cell (data-q absent) → no column highlight, row hover via CSS only.

Also when hovering pivot row → highlight bar: tr mouseenter (delegate via mouseover on tr with data-region) → add .hot to bar rect with same data-region; remove on mouseout.

Bar hover ↔ table: bar g mouseenter → tr.classList.add('rowhl') (give tbody tr:hover style equivalent) + fill accent. Fine.

CSS .rowhl{background:rgba(27,23,16,.045)}.

Count-up util:

```js
function countUp(el, targetCents, dur=1200){
  if(reduced){el.textContent=usd(targetCents);return;}
  const t0=performance.now();
  function tick(t){const p=Math.min(1,(t-t0)/dur);const e=1-Math.pow(1-p,3);el.textContent=usd(Math.round(targetCents*e));if(p<1)requestAnimationFrame(tick);}
  requestAnimationFrame(tick);
}
```
For integer counts similar with plain number formatting.

Apply to: headline amount span, stat numbers, and maybe row/column totals in tfoot & pivot? Could animate totals too — nice touch: animate tfoot totals and grand total after table renders. Keep: animate stat strip + headline. Table totals static (avoid noise). OK maybe animate grand total only. I'll animate headline + stats.

Headline composition: 
`California leads with <em>$16,091.26</em> in cleaned H1 revenue — 72.2% of the total.` 
em accent, serif italic? Accent color, font-weight 600. Compute topRegion & share.

Also dek line computed:
`From ${received} raw rows → ${counted} counted · Q1 ${usd(q1tot)} · Q2 ${usd(q2tot)} · refunds ${usd(refundCents)} netted in.`

Let me write the refund footnote builder:
```js
const refundParts = refunds.map(r=>`${usd(r.amount*100)} ${r.region} ${QMON[q]}`);
```
r.amount dollars *100 cents.

Region×quarter cell building: quarters array qs=[...new Set(dates→q)].sort(). Regions sorted by total desc.

Edge: month undefined if date null (all dates parse here). If date null → treat quarter as null and skip from pivot? Not needed; but code defensively: if d null → quarter 0 bucket "Unparsed"? All parse; just guard: if(!d) continue with excluded count? Keep simple: if date fails, put quarter 0 → won't render column → but then row counted but revenue not attributed... For this dataset all parse. I'll do: if(!d){ // still counted as row, but quarter unknown; assign to quarter 0 } and columns derived from data (0 absent) → its amount then only appears in region total? Region total computed from pivot sum across quarters — I compute totals from quarter sums, so amount in q0 would be dropped silently. To be safe: totals = sum of all clean amounts per region computed separately from clean array (not from pivot quarters). Do that: regionTotal from clean filter. Then quarter cells from pivot. Grand total = sum region totals. Column totals = sum over regions of that quarter (missing→0). Grand via region totals sum. Consistent. Good.

Column totals: qTot(q)=regions reduce.

Now header quarter labels: map q→ {label:`Q${q}`, mo:QMON[q]}.

Write the HTML now, complete.

Also mobile: stats wrap; table font-size shrink via media query; svg scales (width 100%, height auto via viewBox + preserveAspectRatio). For small screens text in svg shrinks — acceptable; maybe set min-width 560px with overflow-x auto container. I'll wrap svg in .chart-wrap{overflow-x:auto} and svg{min-width:560px}.

Write code carefully.

Also the `row label column header` first th: "Region" with sub "cleaned names". Add th[data-q] to quarter headers for hover highlight too? Sure: give thead th data-q.

One more consideration: the user said "no external libraries, everything inline" — no Google fonts, no CDN. Compliant.

Final numbers I expect rendered (sanity): 
Pivot:
California: Q1 $8,744.00, Q2 $7,347.26, total $16,091.26
Texas: Q1 $3,552.60, Q2 $5,940.90, total $9,493.50
Ohio: Q1 $3,982.99, Q2 $2,715.25, total $6,698.24
Column totals: Q1 $16,279.59, Q2 $16,003.41, grand $22,283.00 ✓

Bars: California 16091.26, Texas 9493.50, Ohio 6698.24.

Refund note: "−$450.00 Texas Q1 · −$220.00 Ohio Q2".

Excluded rows detail? Could list the excluded order ids: 1006, 1017, 1028 (N/A, unknown, N/A). Nice detail in footnote: "Excluded: #1006, #1017, #1028 (non-numeric amounts)". Compute dynamically: excludedRows list of ids + raw amount text. Show in footnote: "Non-numeric amounts excluded: #1006 (N/A), #1017 (unknown), #1028 (N/A)". Dynamic. 

Now produce the file. Also brief explanation after code? User said "Output only the complete HTML file." I'll honor that — output just the code block, maybe minimal framing. The instruction from user conflicts with my usual habit of adding explanation; user explicitly said output only the HTML file. I'll output only the code block (perhaps one short sentence is risky; they said only). I'll output just the code.

Hmm, but I generally add a brief explanation... user explicitly overrides. Follow user.

Write the final HTML.

Details in JS for stat strip values: received=31, dupes=1, excluded=3, counted=27, refunds count 2. Count-up integers.

Let me draft the script fully, verifying logic mentally.

CSV string: embed exactly the user's CSV. In template literal, fine.

Potential parsing pitfall: line "1006,2/3/2025,texas ,widget,N/A" — region "texas " trims ✓ amount "N/A" → excluded ✓.

"1011,3/3/2025,Ohio,widget,"$1,999.99"" — the CSV raw shows `"$1,999.99"` quoted. parseAmount: strip $, commas → 1999.99 ✓.

Now the code:

```js
const RAW = `order_id,order_date,...`;
```

Careful with the quotes inside template literal — fine.

parseCSV as above.

Then main computation, DOM building.

Chart SVG creation:

```js
const svgNS='http://www.w3.org/2000/svg';
function el(n,attrs){const e=document.createElementNS(svgNS,n);for(const k in attrs)e.setAttribute(k,attrs[k]);return e;}
```

Build chart with fixed coordinate math.

n=regions.length=3.
labelW=118, plotW=442, gutter=92, padL=6? x offset: labelW starts at 0; bars start x=118. Right edge for value labels: 118+442+92=652. Add small right pad: viewBox width 660.
topPad=6; barH=38; gap=26; plotH=3*38+2*26=166; axisY=6+166=172; tickY=axisY+18=190; svgH=196.

Gridlines from y=2? from topPad-2? draw from 4 to axisY. v loop 0..20000 step 5000: x=118+(v/20000)*442. v=0 → x=118 (axis). Draw vertical lines stroke hairline for v>0; baseline axis line y=axisY from x=118 to x=560 (118+442=560) stroke ink 1.5? 1.

Ticks labels: text-anchor middle at x, y=axisY+16, font 10.5 mono muted: "$0","$5,000","$10,000","$15,000","$20,000".

Bars: i order: California(0), Texas(1), Ohio(2). y_i=6+i*(38+26)=6,70,134. rect x=118,y=y_i,w=0→w_i,h=38, fill ink class .bar. data-region.

Region labels: x=106 (118-12), anchor end, y=y_i+24ish (center +5): y_i+38/2+5.

Value labels: x=118+w_i+12, y=y_i+24, class .vlab mono 13px fill ink; initial opacity 0 → fade in.

Animations: rAF loop per bar with stagger. Implement single animator:

```js
function animateBars(bars){ // bars: [{rect, w, lab}]
  if(reduced){bars.forEach(b=>{b.rect.setAttribute('width',b.w);b.lab.setAttribute('opacity',1);});return;}
  bars.forEach((b,i)=>{
    const t0=performance.now()+i*130; const dur=850;
    function step(t){ const p=Math.max(0,Math.min(1,(t-t0)/dur)); const e=1-Math.pow(1-p,3);
      b.rect.setAttribute('width',(b.w*e).toFixed(1));
      if(p>0.55)b.lab.setAttribute('opacity',Math.min(1,(p-0.55)/0.45));
      if(p<1)requestAnimationFrame(step); else b.lab.setAttribute('opacity',1);
    }
    requestAnimationFrame(step);
  });
}
```
lab opacity start 0.

Hover: on rect (and value label? just rect) mouseenter → fill accent; note text; table row highlight. mouseleave → revert.

Pivot tr hover → find rect[data-region=name] → fill accent + maybe raise? Just fill.

Rect fill via class: .bar{fill:#1b1710;transition:fill .25s} .bar.hot{fill:accent}.

Note default: `3 regions · 27 counted rows · refunds netted in — hover a bar for its quarterly split.` Computed.

Table build with DOM API or string HTML. String HTML simpler. Build rows:

```js
let html='<thead><tr>';
html+='<th scope="col" class="rgn"><span class="q">Region</span><span class="mo">normalized</span></th>';
qs.forEach(q=>{html+=`<th scope="col" data-q="${q}"><span class="q">Q${q}</span><span class="mo">${QMON[q]}</span></th>`});
html+='<th scope="col" class="tot" data-q="tot"><span class="q">H1</span><span class="mo">row total</span></th>';
html+='</tr></thead><tbody>';
```

Wait "H1" as FY label — since quarters only Q1,Q2 present, header "H1 · row total". If full-year data existed it'd be FY. Fine, label "Total".

Rows:
```js
regionsData.forEach(r=>{
 html+=`<tr data-region="${r.region}"><td class="rgn">${r.region}</td>`;
 qs.forEach(q=>{const c=r.quarters.get(q); html+=`<td data-q="${q}">${c==null?'—':usd(c)}</td>`});
 html+=`<td class="tot" data-q="tot">${usd(r.total)}</td></tr>`;
});
```
tfoot:
```js
html+='<tfoot><tr><td class="rgn">Total</td>';
qs.forEach(q=>html+=`<td data-q="${q}">${usd(colTotal(q))}</td>`);
html+=`<td class="tot grand" data-q="tot">${usd(grand)}</td></tr></tfoot>`;
```

Column highlight: cells have data-q in tbody td and tfoot td and thead th. Delegate:

```js
let hlCol=null;
function setCol(q){ if(hlCol===q)return; clearCol(); hlCol=q; if(q) tbl.querySelectorAll(`[data-q="${q}"]`).forEach(c=>c.classList.add('colhl')); }
function clearCol(){ if(hlCol){tbl.querySelectorAll('.colhl').forEach(c=>c.classList.remove('colhl')); hlCol=null;} }
tbl.addEventListener('mouseover',e=>{ const c=e.target.closest('[data-q]'); if(c) setCol(c.dataset.q); });
tbl.addEventListener('mouseleave',clearCol);
```
Hovering region td (no data-q) leaves previous column highlighted until mouseover elsewhere — acceptable; or also clear when no data-q: in mouseover, if no closest → clearCol(). e.target.closest('[data-q]') might find ancestor tr? tr has data-region not data-q. Table cells fine. Add: else clearCol().

Row↔bar linking:
```js
tbl.addEventListener('mouseover',e=>{const tr=e.target.closest('tr[data-region]'); if(tr) hotBar(tr.dataset.region,true);});
tbl.addEventListener('mouseout',e=>{const tr=e.target.closest('tr[data-region]'); if(tr) hotBar(tr.dataset.region,false);});
```
Combine into same mouseover listener (two listeners fine).

hotBar: rects svg querySelector `rect[data-region="..."]` toggle class hot.

Bar listeners similar toggle tr .rowhl + note.

Note update on bar hover:
```js
function noteFor(r){return `${r.region} · ${r.orders} orders counted · Q${...}`;}
```
Compose: `${r.region} — ${r.orders} orders · ` + qs.map(q=>`Q${q} ${usd(r.quarters.get(q)||0)}`).join(' · ')

Default note variable stored to restore.

Stat strip: build HTML then count-ups.

Headline: 
```js
const top=regionsData[0];
const share=(top.total/grand*100);
headline.innerHTML=`${top.region} leads with <em id="topAmt"></em> — <span class="pct">${share.toFixed(1)}%</span> of all cleaned revenue.`;
```
pct styled smaller? Keep same size serif. Count-up topAmt.

Dek: 
`From ${received} raw export rows → ${counted} counted · Q1 ${usd(q1Tot)} · Q2 ${usd(q2Tot)} · ${refundCount} refunds (${usd(refundCents)}) netted as negative revenue.`

Where q1Tot=colTotal(1) etc. Since qs may vary, build from qs: qs.map(q=>`Q${q} ${usd(colTotal(q))}`).join(' · '). Good.

Footnotes under table: two lines mono muted:
line1: `Excluded from revenue: ${excludedList}` where excludedList = excludedRows.map(r=>`#${r.id} (${r.raw})`).join(', ') — ids 1006 (N/A), 1017 (unknown), 1028 (N/A).
line2: `Refunds counted as negative revenue: ${refundParts.join(' · ')}` → "−$450.00 Texas Q1 · −$220.00 Ohio Q2".
line3 maybe: `Duplicates dropped: #1008 (kept first occurrence)` — dynamic: dupIds list. dupes list of ids: ['1008'].

Method footer: rules sentence.

Let me now write out the full file text. Keep CSS tidy.

Also set <html lang="en">.

One concern: `usd` on cents uses toLocaleString — fine.

Also negative display uses U+2212 minus.

Colors:
--paper:#f6f1e6; --ink:#1c1812; --hair: rgba(28,24,18,.16); --hair2: rgba(28,24,18,.34); --mut: rgba(28,24,18,.56); --acc:#a63a24;

Selection color maybe accent-tinted.

Bar fill: ink; gridlines hair; axis hair2; value labels ink; region labels ink serif.

Body background paper; maybe subtle top border thick ink via main border-top? The masthead rule covers it.

Media query max-width 680px: table font sizes smaller; hide center masthead span; stat padding smaller; h1 smaller handled by clamp.

Table overflow on mobile: wrap .tbl-wrap{overflow-x:auto} with table min-width 520px.

Write everything.

Also double-check CSV parser newline handling with \r\n: file may have \n only; handle both as written.

Empty-row filter: `row.some(f=>f.trim()!=='')` — but rows array at newline: I push row always then check. In my loop I wrote: on newline: row.push(field); then if row.length && row.some(...) rows.push(row). Also reset. But careful about the header detection. Let me finalize function:

```js
function parseCSV(text){
  const rows=[]; let row=[],field='',inQ=false;
  const pushRow=()=>{ if(row.length&&row.some(f=>f.trim()!=='')) rows.push(row); row=[]; };
  for(let i=0;i<text.length;i++){
    const c=text[i];
    if(inQ){
      if(c==='"'){ if(text[i+1]==='"'){field+='\"';i++;} else inQ=false; }
      else field+=c;
    }else if(c==='"') inQ=true;
    else if(c===','){ row.push(field); field=''; }
    else if(c==='\n'){ row.push(field); field=''; pushRow(); }
    else if(c==='\r'){ if(text[i+1]==='\n') i++; row.push(field); field=''; pushRow(); }
    else field+=c;
  }
  row.push(field); pushRow();
  return rows;
}
```
Wait: field with escaped quote inside like `"1,240.00"` — no internal quotes in data. OK. Note field+='"' need escaping in template? It's inside <script> normal JS — `field += '"'` fine.

Header: rows[0] = header (5 cols). Data rows: rows.slice(1), each should have 5 fields. Trailing empty line at end: final pushRow with row=[''] filtered out ✓.

Main loop guard r.length>=5.

Time to compose final answer. Also `<em>` in h1 styled: font-style normal? Keep italic serif for the amount? Italic Georgia numerals look nice; but red accent — I'll style em{font-style:normal;color:acc}.

Small detail: headline one line — ensure no wrap on desktop; allow wrap on mobile (fine).

Also add title element.

Stat strip HTML:

```html
<section class="quality" id="quality" aria-label="Data quality">
  <div class="stat"><span class="num" id="stRec">0</span><span class="lab">Rows received</span></div>
  <div class="stat"><span class="num" id="stDup">0</span><span class="lab">Duplicates dropped</span></div>
  <div class="stat"><span class="num" id="stExc">0</span><span class="lab">Excluded · non-numeric</span></div>
  <div class="stat"><span class="num" id="stCnt">0</span><span class="lab">Rows counted</span></div>
  <div class="stat"><span class="num acc" id="stRef">0</span><span class="lab">Refunds signed</span><span class="sub" id="refNet"></span></div>
</section>
```
Style .stat{display:flex;flex-direction:column;...}. num serif 40px; lab mono 10px uppercase ls .14em mut; sub mono 11px acc.

Stat strip container: border-top/bottom hairline; stats padding: 20px 26px 18px 0; margin-right:26px; border-right hair; last-child border none. Use flex-wrap.

Count-up ints: countInt(el,target).

Refunds net sub: `−$670.00 netted` in acc.

Now the footnote under table and method footer.

Method footer text:

"Cleaning rules applied — Dedupe by order_id, first occurrence kept · Amounts that fail numeric parsing (N/A, unknown, blank) excluded from revenue and reported above · Negative amounts treated as refunds and summed as negative revenue · Region names normalized to Texas / California / Ohio · Dates parsed from ISO (2025-01-06), slash (1/9/2025) and long (Jan 21, 2025) formats · Quarters calendar-aligned: Q1 = Jan–Mar, Q2 = Apr–Jun.
All figures are computed in the browser from the raw export; nothing is hard-coded."

Nice authored close.

Section numbering: 01 Ledger quality (the strip) — actually strip sits before sections; give it its own sec-head "01 — Data quality". Then 02 pivot, 03 chart. Order: headline → 01 data quality strip → 02 pivot → 03 chart → method.

Hmm spec order: pivot, bar chart, quality panel, headline. Headline top ✓. I'll order sections: 01 Data quality, 02 Pivot, 03 Chart — reasonable narrative (clean → report). Fine.

Write final HTML now, being careful with JS string building and escaping in attributes (region names plain).

Also `qs` derived: 
```js
const qset=new Set(); clean.forEach(x=>{ if(x.q) qset.add(x.q); }); const qs=[...qset].sort();
```
x.q = quarter from date. If date null, x.q=0 → not in qset; that row's amount still in region total via clean sum but missing from a column — acceptable defensive behavior (never happens here).

regionsData:
```js
const regionsData=[...pivot.keys()].map... 
```
pivot only includes rows with q — rows with q=0 skipped in pivot building? In pivot build: `const q=x.q; if(!q) ... still add under 0?` Simpler: build region totals from clean; build quarter maps from clean (skip q=0). Then regions set from clean (all rows). Let me restructure:

```js
const regionSet=new Set(); clean.forEach(x=>regionSet.add(x.region));
const regionsData=[...regionSet].map(rg=>{
  const rowsR=clean.filter(x=>x.region===rg);
  const qm=new Map();
  rowsR.forEach(x=>{ if(x.q) qm.set(x.q,(qm.get(x.q)||0)+x.amountCents); });
  const total=rowsR.reduce((s,x)=>s+x.amountCents,0);
  const orders=rowsR.length;
  return {region:rg,quarters:qm,total,orders};
}).sort((a,b)=>b.total-a.total);
```

colTotal(q)=regionsData.reduce((s,r)=>s+(r.quarters.get(q)||0),0);
grand=regionsData.reduce((s,r)=>s+r.total,0);

Refunds: clean.filter(x=>x.amountCents<0).

Excluded list: track during loop: excludedRows.push({id:r[0].trim(), raw:r[4].trim()}).

Dup ids: dupIds.push(id).

usd handles cents.

Count-up ints formatting plain.

Final check on QMON: const QMON={1:'Jan – Mar',2:'Apr – Jun',3:'Jul – Sep',4:'Oct – Dec'};

Bar chart note default: `${regionsData.length} regions · ${counted} counted rows · hover a bar for its quarterly split`.

Alright, compose. Also chart svg needs aria-label.

CSS for svg text classes:
.bar{fill:var(--ink)} .bar.hot{fill:var(--acc)}
.vlab{font:13px var(--mono);fill:var(--ink)}
.rlab{font:italic 15px var(--serif); fill:var(--ink)}
.tick{font:10.5px var(--mono);fill:var(--mut)}
.grid{stroke:var(--hair)} .axis{stroke:var(--hair2)}

CSS variables in SVG fill via class fine.

Region label italic serif — nice ledger touch.

Let me now also compute plotW so California value label fits: viewBox width W = 118+442+12+~78+pad → 118+442=560; label starts 474+12=486; "$16,091.26" at 13px mono ≈ 10 chars ×7.8 = 78 → ends 564. W=660 leaves margin ✓.

Tick label "$20,000" at x=560 anchor middle → extends to 578 < 660 ✓. "$0" at x=118 → fine.

Now headline em id="topAmt" count-up to 1609126 cents.

Also animate strip numbers after DOM ready.

prefers-reduced-motion: const reduced=matchMedia('(prefers-reduced-motion: reduce)').matches.

Assemble script order: RAW → parseCSV → parse fns → compute → render headline/dek → render quality (after count-up) → render table → render chart → wire interactions → run animations.

Everything in one IIFE at end of body.

Also pivot table row hover CSS: tbody tr[data-region]:hover, tr.rowhl {background:rgba(28,24,18,.05)}.

Column highlight: .colhl{background:rgba(166,58,36,.06)}? Accent-tinted column highlight could be nice and distinguishable from row ink tint. Use rgba(166,58,36,.07). And row hover ink tint. Combined = crosshair with two tints. Good, subtle.

tfoot .colhl also applies.

thead th.colhl too.

Write the code. Also ensure `usd` negative uses minus U+2212 — in JS string '\u2212'.

Grand total cell class grand: maybe font-size 14.5 and 2px double border-top? tfoot td border-top:2px solid ink already. Grand: color acc? Keep ink bold; maybe add small "100%"? no.

One more: headline text should be a "one-line headline stating the top region and its total" — mine does that ✓.

Also dek uses spans with hair separators.

Compose final HTML file text. Watch out: inside <script>, the CSV contains no backticks/`${` — safe in template literal.

Chart annotation element placement: between sec-head and svg: `<p class="note" id="chartNote"></p>` mono 12px mut; margin-bottom 14.

Also note transitions? Text swap instant fine.

Let me write bars' data-region on rect and on g.

Bar hover targets: rect only (value label might intercept—set pointer-events:none on labels). Set .vlab,.rlab{pointer-events:none}.

Table min-width 560px within .tbl-wrap overflow auto.

Quality strip on narrow: allow horizontal scroll? flex-wrap fine.

I think ready. Write final answer: only the HTML file in a code block.
