Academic Paper（学术论文风）

A locked, single-theme deck plugin in the html-ppt-studio family, ported from the MIT-licensed lewislulu/html-ppt-skill academic-paper theme (assets/themes/academic-paper.css on the upstream templates/deck.html scaffold). The register is a LaTeX article walking on stage: paper-white ground, ink-black serif text, link-blue underlined citations, italic kickers, hairline rules everywhere, zero rounded corners, no shadows. It reads like Computer Modern even when Computer Modern is not installed.

Start from example.html in this plugin folder. It is the proven seed: keep its :root token sheet, base/slide-system CSS, academic device classes, deck chrome and the entire navigation script verbatim, then replace only the slide content. Do not rewrite the design system, and do not introduce any color or font outside this spec.

Design tokens (locked — reproduce verbatim in :root)

css
:root{
  --bg:#fdfcf8; --bg-soft:#f7f5ed; --surface:#ffffff; --surface-2:#f5f3ea;
  --border:rgba(20,20,20,.14); --border-strong:rgba(20,20,20,.35);
  --text-1:#0a0a0a; --text-2:#333333; --text-3:#707070;
  --accent:#1a3a7a;   /* link blue — citations, "ours" data, best numbers */
  --accent-2:#0a0a0a; /* ink — rules, heavy structure */
  --accent-3:#8a1a1a; /* sparing dark red — errata/negative only */
  --good:#1a5a2a; --warn:#8a6a1a; --bad:#8a1a1a;
  --grad:linear-gradient(135deg,#1a3a7a,#0a0a0a);
  --grad-soft:linear-gradient(135deg,#e8edf8,#f5f3ea);
  --radius:0px; --radius-sm:0px; --radius-lg:0px;
  --shadow:none;
  --shadow-lg:0 1px 2px rgba(0,0,0,.1);
  --font-sans:'Latin Modern Roman','Playfair Display','Noto Serif SC',Georgia,serif;
  --font-serif:'Latin Modern Roman','Playfair Display','Noto Serif SC',Georgia,serif;
  --font-mono:'JetBrains Mono',SFMono-Regular,Menlo,monospace;
  --font-display:'Latin Modern Roman','Playfair Display','Noto Serif SC',Georgia,serif;
  --letter-tight:-.01em; --letter-normal:0;
  --ease:cubic-bezier(.4,0,.2,1);
}

Hard color discipline: paper white, ink black, link blue, and the three semantic statuses are the entire palette. --accent-3 dark red appears only for errata, negative deltas or "withdrawn/deprecated" marks. Never add gradients beyond the two declared tokens, never round a corner, never cast a shadow stronger than --shadow-lg.

Typography

• All three display slots are serif. Latin Modern Roman is named first

so machines with LaTeX fonts get the real thing; Playfair Display (+ Noto Serif SC for CJK, then Georgia) is the webfont fallback. Google Fonts @import for Playfair Display (incl. italics), Noto Serif SC and JetBrains Mono are the only permitted external references.

• Headings weight 700, body 400, line-height 1.6. No uppercase headings, no

negative tracking beyond --letter-tight:-.01em.

• .kicker is the theme signature: italic, link blue, sentence case,

letter-spacing:0, weight 400 — never uppercase, never bold.

• Numbers in stats/tables use font-variant-numeric:tabular-nums.

Academic devices (theme-signature components — use them)

| class | device | |---|---| | .rule / .rule-double | hairline rule / LaTeX titlepage double rule (2px over 1px) | | .abstract | italic abstract environment between two hairline rules, bold lead word | | .cite | [n] citation anchor — mono, link blue, underlined | | .figure + .figcaption | ruled figure box with numbered italic caption (<b>Figure 1:</b> …) | | .booktabs | three-line table: 2px top/bottom rules, 1px header rule, no vertical rules; .best bolds winners in link blue | | .footnote | dagger small print under a hairline rule | | .references | hanging [n] bibliography list, titles in <i> | | .toc-list | numbered outline with hairline separators and italic timing column | | .section-num | oversized ghost numeral (in --surface-2) for section dividers |

Every figure and table must carry a numbered caption — that is what makes the deck feel like a paper. Diagrams are ink-line inline SVG (1.5px ink strokes, serif labels, the "ours" box tinted #e8edf8/link blue); charts are pure CSS bars on a heavy ink axis with baselines in muted --surface-2 and exactly one link-blue "ours" bar. No chart libraries, no remote images.

Layout masters (all demonstrated in example.html, 11 pages)

1. cover — italic venue kicker, double rule, serif title, author line with

superscript affiliations, hairline rule, affiliation small print

1. toc/outline — .toc-list numbered contents
2. section-divider — ghost numeral + ink rule
3. abstract + contributions — .abstract beside a .check list
4. stat-highlight — one giant tabular number in link blue + .footnote CI
5. method figure — inline SVG pipeline in .figure with Figure caption
6. chart-bar — CSS bar chart, muted baselines vs blue "ours", Figure caption
7. booktabs table — Table caption, .best winners
8. big-quote — italic serif epigraph with precise attribution
9. conclusions — two ruled cards (shown / open problems) + artifact link
10. thanks/references — .references bibliography + contact line

Compose decks from these masters; sequence cover → outline → (divider → 2–4 content pages) × N → conclusions → references.

Slide system & runtime (keep verbatim)

• One self-contained HTML file; inline <style> + <script>; zero build,

zero external JS. Each page is <section class="slide" data-title="…"> inside <div class="deck" id="deck"> — a horizontal scroll-snap strip, one 100vw × 100vh screen per slide (16:9 / 1280×720 baseline, fluid via clamp()), padding 72px 96px, no internal scrolling.

• Fixed chrome: .deck-header (running head: short title · venue, italic),

.deck-footer (attribution + N / total counter), 2px .progress-bar in link blue.

• Keyboard: ←/→/Space/PageUp/PageDown/Home/End; #/N hash deep links via

history.replaceState in try/catch (srcdoc-safe). The script's dual capture-phase listeners with Event-identity dedupe, .deck scroll sync and body auto-focus fix real iframe-host bugs — do not simplify them away. This variant is theme-locked: there is no T theme cycling.

• Speaker notes: one hidden <div class="notes">…</div> per slide.
• Animations are restrained: at most one anim-rise-in/anim-fade-up hero

plus one anim-stagger-list per slide. No 3D, no glitch, no confetti — this is a lecture hall, not a launch party.

Authoring checklist

1. Copy example.html; keep all <style> blocks and the <script> verbatim.
2. Replace the 11 demo slides with your content using the masters above.
3. Real content, real numbers, real (or plausibly fictional) citations — no

lorem ipsum; number every Figure/Table caption consecutively.

1. Keep the running head and footer attribution updated; the script computes

the N / total counter automatically.

1. Write 1–3 sentence speaker notes per slide in .notes.
2. Verify: arrows + Space navigate, #/5 deep-links, no slide overflows

vertically, no color or font outside the token sheet.
