Y2K Chrome (hps-y2k-chrome)

Single-theme deck plugin locked to the y2k-chrome theme from the upstream MIT-licensed lewislulu/html-ppt-skill (36 themes × 31 layouts × 27 animations — this plugin ships exactly one of those skins, fully baked into one self-contained seed: example.html).

Start from example.html. Replace content only. Never rewrite the design system or the runtime script. No colors or fonts outside this spec.

Fonts: Space Grotesk is both display and body type ('Noto Sans SC' fallback for CJK), JetBrains Mono for code/labels. Loaded via Google Fonts @import only — the sole permitted external resource.

Signature devices (use these, nothing else)

1. Silver-metal canvas — body carries the full-bleed 5-stop gradient linear-gradient(135deg,#c4cfe0 0%,#f0f3f8 25%,#aab8d0 50%,#f5f7fb 75%,#b8c4d8 100%). Every slide is transparent over it. Never paint an opaque slide background.
2. Chrome-clipped type — .h1, .chrome-text, .stat-big clip --chrome-text (white→steel→gunmetal) via background-clip:text, plus filter:drop-shadow(0 2px 3px rgba(40,55,85,.38)) so the white top stop keeps letter definition over the light canvas. Display numerals and hero words are always chrome, never flat color.
3. Frosted-glass cards — .card = --surface (72% white) + backdrop-filter:blur(16px) saturate(140%) + --shadow. The inset 0 1px 0 rgba(255,255,255,.9) top highlight is the signature — never drop it. Mega radius --radius:26px (lg surfaces 36px).
4. Candy accents — purple --accent leads (kickers, progress bar, checks), aqua --accent-2 and pink --accent-3 support (orbs, chart bars, eyebrow tints). Accents are for small surfaces only; large fills use --grad / --grad-soft.
5. Glossy orbs — .orb radial-gradient candy spheres with a white specular highlight, absolutely positioned, z-index:0, decor only.
6. Chrome sparkles — inline 4-point star SVGs (.sparkle) filled with the chrome gradient or candy accents.
7. Chrome capsule pills — .pill = linear-gradient(180deg,#fff,#d4dcec) with --border stroke; .pill-accent tints with --accent.

Forbidden: dark mode, neon-on-black, hard offset shadows, flat untextured H1 color, any hex value or font family not listed above.

Page structure & runtime (keep verbatim from the seed)

• One self-contained HTML file: inline <style> + inline <script>, zero build, zero external JS. Charts are pure CSS / inline SVG — never Chart.js or mermaid. Icons are inline SVG. No external images.
• Every page is <section class="slide" data-title="…"> inside <div class="deck" id="deck"> — a horizontal scroll-snap strip, one 100vw × 100vh screen per slide, padding 72px 96px, no internal scrolling.
• Fixed chrome: .deck-header (deck name + y2k-chrome theme chip), .deck-footer (attribution + N / total counter), .progress-bar (accent fill).
• Keyboard runtime: ← → Space PageUp PageDown Home End navigate; #/N (1-based) hash deep-links with history.replaceState in try/catch (srcdoc-safe). The script dedupes the 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. This variant is theme-locked: no T cycling.
• Speaker notes: one hidden <div class="notes">…</div> per slide.

Layout masters (upstream 31-layout catalog)

Composition default: cover → toc → (section-divider → 2–4 content pages) × N → cta/thanks. The seed demonstrates 11 masters: cover, toc, section-divider, two-column, kpi-grid, stat-highlight, chart-bar, process-steps, comparison, big-quote, thanks.

Class vocabulary (replace content, not classes): typography .eyebrow .kicker .h1 .h2 .h3 .h4 .lede .dim .dim2 .mono .chrome-text .gradient-text; layout .row .row.wrap .grid .g2 .g3 .g4 .center .mt-s/.mt-m/.mt-l; components .card .card-soft .card-accent .pill .pill-accent .divider-accent .section-num .kpi .stat-big .bar-chart .steps .quote .check .orb .sparkle.

Animations (upstream subset inlined in the seed): anim-rise-in, anim-fade-up, anim-stagger-list. Restraint rule: at most one hero animation plus one stagger per slide.

Authoring checklist

1. Copy example.html; keep all <style> blocks and the <script> verbatim.
2. Replace the 11 demo slides with the planned layout sequence; the script computes the N / total counter automatically.
3. Real content, real numbers — no lorem ipsum, no placeholder images.
4. Write 1–3 sentence speaker notes per slide in .notes.
5. Verify: arrows + Space navigate, #/5 deep-links, every H1 reads as chrome over the metal canvas, no slide overflows vertically.
