Memphis Pop（孟菲斯波普）

A locked single-theme deck plugin: the memphis-pop skin from the upstream MIT-licensed lewislulu/html-ppt-skill (36 themes × 31 layouts), shipped as one self-contained seed — example.html — that carries the full token sheet, the Memphis decor devices, the slide scaffold, and the keyboard runtime.

Start from example.html. Replace content only. Never rewrite the design system or the runtime script. Never introduce colors or fonts outside this spec.

Positioning vs. sibling Memphis-adjacent plugins: this is the full-bleed scattered confetti-dot pattern Memphis. daisy-days is hand-drawn daisy childlike (flower illustration devices), block-frame is big-color-block neobrutalist (no pattern). The three decor systems are mutually exclusive — do not mix.

Locked token sheet (do not deviate)

Every variable below is defined in the seed's :root. Slides reference tokens only — never hard-code a color in slide markup.

:root{
  --bg:#fef6e8;            /* warm cream canvas */
  --bg-soft:#fdebc7;
  --surface:#ffffff;       /* card face */
  --surface-2:#fff1d1;
  --border:#111111;        /* everything outlines in near-black */
  --border-strong:#111111;
  --text-1:#111111; --text-2:#333333; --text-3:#666666;
  --accent:#ff3d8b;        /* hot pink — the lead */
  --accent-2:#37c2d7;      /* teal */
  --accent-3:#ffcc00;      /* yellow */
  --good:#6ac04c; --warn:#ffcc00; --bad:#ff3d8b;
  --grad:linear-gradient(135deg,#ff3d8b,#ffcc00 50%,#37c2d7);
  --grad-soft:linear-gradient(135deg,#fdebc7,#fff1d1);
  --radius:10px; --radius-sm:6px; --radius-lg:18px;
  --shadow:5px 5px 0 #111;     /* hard offset, never blurred */
  --shadow-lg:9px 9px 0 #111;
  --font-sans:'Space Grotesk','Inter','Noto Sans SC',sans-serif;
  --font-serif:'Space Grotesk','Noto Sans SC',sans-serif;
  --font-mono:'JetBrains Mono',SFMono-Regular,Menlo,monospace;
  --font-display:'Archivo Black','Space Grotesk',sans-serif;
  --letter-tight:-.01em; --letter-normal:0;
  --ease:cubic-bezier(.4,0,.2,1);
}

Fonts come from Google Fonts @import only (Archivo Black, Space Grotesk, Noto Sans SC, JetBrains Mono). No other external resource of any kind.

Signature decor devices (the Memphis kit)

1. Confetti-dot canvas — the body background tiles three offset radial-gradient layers of 3px dots (pink / teal / yellow at 200 / 220 / 260px tile sizes) over --bg. It is full-bleed on every slide; slides stay transparent so the pattern always shows through. Never paint an opaque slide background.
2. Black-outlined cards — .card is 2.5px solid #111 with --shadow (hard offset, zero blur). Hero cards may use --shadow-lg.
3. Geometric SVG confetti — inline SVG triangles, squiggle zigzags, circles, plus signs and half-tone arcs, each stroked in #111 and filled with one accent, scattered absolutely behind/around content (.memphis-shape). 2–4 per slide maximum.
4. Tilted sticker pills — .pill carries a 2px black border, an accent fill and a slight rotate(±2deg); used as tags and badges.
5. Thick black divider bars — .divider-accent is a hot-pink bar with a black outline; section dividers pair it with a giant outlined numeral.
6. Gradient display numerals — .gradient-text (the tri-color --grad) is reserved for big numbers and 1–2 highlight words.

Layout system (shared upstream 31-layout catalog)

The upstream catalog is shared across the html-ppt family; compose pages from these master categories:

Default sequence: cover → toc → (section-divider → 2–4 content pages) × N → thanks. Charts are always pure CSS or inline SVG — never Chart.js or any external library. The seed demonstrates: cover, toc, section-divider, two-column, kpi-grid, stat-highlight, chart-bar, process-steps, big-quote, thanks.

Page structure & runtime contract (keep the seed script verbatim)

• Every page is <section class="slide" data-title="..."> inside <div class="deck" id="deck"> — a horizontal scroll-snap strip, each slide exactly 100vw × 100vh (one screen, no internal scrolling), 16:9 / 1280×720 baseline with clamp() type scales, padding 72px 96px.
• Fixed chrome: .deck-header (deck title + theme chip), .deck-footer (attribution + N / total counter), .progress-bar.
• Keyboard: ← → Space PageUp PageDown Home End navigate.
• Hash routing: #/N (1-based) deep-links a slide; navigation syncs the hash via history.replaceState wrapped in try/catch (srcdoc-safe).
• The script dedupes dual window/document capture-phase key listeners by Event identity and auto-focuses <body> so keys work without a click — these solve real iframe-host bugs; do not "simplify" them away.
• Speaker notes: one hidden <div class="notes">…</div> per slide.

Authoring checklist

1. Copy example.html; keep all <style> blocks and the <script> verbatim.
2. Replace the 10 demo slides with the planned layout sequence; real content, real numbers — no lorem ipsum, no placeholder images.
3. Keep the confetti-dot canvas visible on every slide; scatter at most 2–4 geometric SVG shapes per slide.
4. Stay inside the locked palette: pink leads, teal/yellow support, near-black #111 outlines, white card faces — nothing else.
5. Write 1–3 sentence speaker notes per slide in .notes.
6. Verify: arrows + Space navigate, #/5 deep-links, no slide overflows vertically, every shadow is a hard offset (no blur anywhere).
