# Y2K Chrome (hps-y2k-chrome) Single-theme deck plugin locked to the `y2k-chrome` theme from the upstream MIT-licensed [`lewislulu/html-ppt-skill`](https://github.com/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.** ## Locked token sheet (`:root` — do not add, remove, or recolor) ```css :root{ --bg:#dfe4ec; --bg-soft:#eef1f6; --surface:rgba(255,255,255,.72); --surface-2:rgba(255,255,255,.5); --border:rgba(120,135,170,.32); --border-strong:rgba(80,100,140,.55); --text-1:#1a1f2e; --text-2:#4a536a; --text-3:#8590a6; --accent:#8a5cff; --accent-2:#3ccfd8; --accent-3:#ff84c4; --good:#1fb98c; --warn:#e8a13d; --bad:#e0445a; --grad:linear-gradient(135deg,#b8c4d8 0%,#f5f7fb 30%,#8a9ab8 55%,#e8ecf4 80%,#6b7a95 100%); --grad-soft:linear-gradient(135deg,#c9e4ff,#f5d6ff 50%,#d6fffa); --chrome-text:linear-gradient(180deg,#f8faff 0%,#9aa8c4 50%,#4a5670 100%); --radius:26px; --radius-sm:16px; --radius-lg:36px; --shadow:0 12px 30px rgba(70,90,130,.22),inset 0 1px 0 rgba(255,255,255,.9),inset 0 -1px 0 rgba(80,100,140,.2); --shadow-lg:0 24px 60px rgba(70,90,130,.35),inset 0 2px 0 rgba(255,255,255,.95); --font-sans:'Space Grotesk','Inter','Noto Sans SC',sans-serif; --font-display:'Space Grotesk','Inter',sans-serif; --font-mono:'JetBrains Mono',SFMono-Regular,Menlo,monospace; --letter-tight:-.03em; --letter-normal:-.01em; --ease:cubic-bezier(.4,0,.2,1); } ``` 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) | group | layouts | |---|---| | Openers & transitions | `cover` `toc` `section-divider` | | Text-centric | `bullets` `two-column` `three-column` `big-quote` | | Numbers & data | `stat-highlight` `kpi-grid` `table` `chart-bar` `chart-line` `chart-pie` `chart-radar` | | Code & terminal | `code` `diff` `terminal` | | Diagrams & flows | `flow-diagram` `arch-diagram` `process-steps` `mindmap` | | Plans & comparisons | `timeline` `roadmap` `gantt` `comparison` `pros-cons` `todo-checklist` | | Visuals | `image-hero` `image-grid` | | Closers | `cta` `thanks` | 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. ## Attribution Visual system, token vocabulary, layout taxonomy, and the y2k-chrome palette come from the upstream MIT-licensed [`lewislulu/html-ppt-skill`](https://github.com/lewislulu/html-ppt-skill) (© lewis &lt;sudolewis@gmail.com&gt;).
