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)

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 --accent-3 dark red appears only for errata, negative deltas or "withdrawn/deprecated" marks.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)

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.
