The "midnight-editorial" slide-deck preset from nicobailon/visual-explainer, locked as a single-aesthetic deck plugin. Use when the user wants a dramatic, magazine-grade dark presentation — engineering reviews, product keynotes, editorial launches, anything that should feel like a midnight issue of a serious journal. triggers:

Midnight Editorial（午夜金辉）

A single-aesthetic deck plugin: the midnight-editorial preset from the upstream MIT-licensed nicobailon/visual-explainer skill (templates/slide-deck.html), pinned and shipped as one self-contained seed — example.html. The upstream mermaid diagram slide has been replaced by a pure CSS/SVG pipeline page; the deck has zero external JS dependencies (Google Fonts @import is the only external reference).

Signature combination (what makes this skin this skin):

1. Deep navy + warm gold — #0f1729 page, #d4a73a accent, parchment text #e8e4d8. Cinematic, magazine-grade, dramatic.
2. Serif display → mono label drop — Instrument Serif at up to 120px (clamp(48px,10vw,120px), weight 400, -2px tracking, 0.95 line-height) falling directly to 13–14px uppercase JetBrains Mono labels with 1.5px letter-spacing. No intermediate sans anywhere.
3. Gold radial accent glow — every content slide carries one radial-gradient(ellipse at X% Y%, var(--accent-dim) 0%, transparent ~40%) inline background, with the ellipse anchor moving per slide.
4. Gold SVG corner marks + ghost numerals — 2px gold corner line marks at opacity 0.15 on the title slide; dividers carry a ghost clamp(100px,22vw,260px) gold numeral at opacity 0.06.
5. Cinematic staggered transitions — slides enter with fade + translateY(40px) + scale(0.98) on cubic-bezier(0.16,1,0.3,1); .reveal children stagger at 0.1s increments (max 6).
6. SlideEngine dual theme — explicit dark/light toggle (T key + ◐ chrome button, html[data-theme]), defaulting to the OS preference. The light mode is a locked cream/gold skin, not an afterthought.

Start from example.html. Replace content only — never rewrite the design system or the runtime script, and never introduce colors or fonts outside the token sheets below.

Locked token sheet — dark (default)

:root {
  --font-body: 'Instrument Serif', Georgia, serif;
  --font-mono: 'JetBrains Mono', 'SF Mono', Consolas, monospace;

}

Locked token sheet — light (html[data-theme="light"])

html[data-theme="light"] {
  --bg: #faf8f2;
  --surface: #ffffff;
  --surface2: #f5f0e6;
  --surface-elevated: #fffdf5;
  --border: rgba(30, 30, 50, 0.08);

  --accent-dim: rgba(184, 134, 11, 0.08);
  --code-bg: #2a2520;

  --blue: #2563eb;   --blue-dim: rgba(37, 99, 235, 0.08);
}

The same light block is mirrored under @media (prefers-color-scheme: light) { html:not([data-theme]) { … } } as a no-JS fallback. Both themes are part of the contract — every slide you author must read correctly in both. Semantic colors (--green/--red/--blue) are for status only (trends, before/after labels, diagram node families) — never decorative.

Fonts (locked — Google Fonts @import only)

No third font. No bold serif — drama comes from size, not weight.

Typography scale (locked)

Layout masters (compose 8–15 pages from these)

Decorative devices (locked)

• One gold radial glow per content slide (inline background-image, var(--accent-dim) ellipse, anchor varies per slide — never two glows).
• Gold corner-mark SVGs (2px lines, opacity 0.15) on the title slide.
• Ghost gold numerals on dividers; ghost quote mark on quote slides.
• Decorative asides are inline SVG only — circles/lines in theme colors with a mono caption. No icon fonts, no images, no external assets.
• At most 6 .reveal children per slide (stagger delays stop at 0.6s).

Page structure & runtime (locked)

• Single self-contained HTML file; <div class="deck"> containing <section class="slide slide--…"> pages; vertical scroll-snap, one viewport (100dvh) per slide, no internal scrolling.
• SlideEngine builds all chrome at runtime: gold 3px progress bar, right-edge dot rail, mono counter, fading hints, ◐ theme button.
• Navigation: ←/→/Space/PageUp/PageDown/Home/End keys, touch swipe, scroll-snap wheel; #/N hash routing (restored on load, updated on slide change); T toggles dark/light.
• prefers-reduced-motion disables all transitions; responsive height breakpoints (700/600/500px) and a 768px width breakpoint are part of the contract.

Hard rules

1. Start from example.html; replace slide content only. Do not rewrite the CSS or the SlideEngine script.
2. No colors or fonts outside the two locked token sheets. No new hex values.
3. Both themes must work — check every slide in dark and light.
4. Zero external JS: no mermaid, no Chart.js, no CDN scripts. Diagrams and charts are pure CSS/SVG using the masters above. Google Fonts @import is the only allowed external reference.
5. Real content, real numbers — no lorem ipsum. Replace all fictional "Nocturne" demo content.
6. 8–15 slides; always open with .slide--title and close with .slide--bleed or .slide--quote.
