Electric Studio · 钴蓝工作室

Bold, clean, professional, high-contrast split-panel decks. Theme locked to the Electric Studio preset (section 2 of STYLE_PRESETS.md) from the MIT-licensed zarazhangrui/frontend-slides.

Start from example.html in this plugin folder. It is the proven seed: keep its stage CSS (full viewport-base.css contents), the split-panel shell, the corner-marks chrome, the :root tokens, and the entire SlidePresentation controller script verbatim — replace slide content only. Do not rewrite the design; do not introduce any color or font outside this spec.

Locked design tokens (:root — complete list, no additions)

:root {
    --bg-dark: #0a0a0a;                          /* edge bar, dark text, stage letterbox */
    --bg-white: #ffffff;                         /* upper panel */
    --accent-blue: #4361ee;                      /* cobalt panel, chips, bars, numerals */
    --text-dark: #0a0a0a;
    --text-light: #ffffff;
    --text-dark-soft: rgba(10, 10, 10, 0.58);
    --text-light-soft: rgba(255, 255, 255, 0.72);
    --line-dark: rgba(10, 10, 10, 0.14);
    --line-light: rgba(255, 255, 255, 0.28);
    --blue-soft: rgba(67, 97, 238, 0.10);        /* tick boxes, outline bar fills */

    --stage-bg: var(--bg-dark);
    --slide-bg: var(--bg-white);

    --font: 'Manrope', sans-serif;               /* the ONLY typeface */
    --title-size: 152px;
    --h2-size: 88px;
    --lede-size: 33px;
    --body-size: 27px;

    --slide-pad-x: 110px;
    --edge-bar-h: 14px;

    --ease-out-expo: cubic-bezier(0.16, 1, 0.3, 1);
    --duration-normal: 0.7s;
}

Forbidden: any other hue, gradients, purple/indigo (#6366f1), warm accents, photography, illustrations, drop shadows, rounded hero cards. The palette is exactly white / cobalt / near-black plus their soft alphas.

Typography (all Manrope, Google Fonts weights 400/500/800)

• Display / H2 — Manrope 800, tight negative letter-spacing (-0.025em to -0.035em), line-height ≤ 1.08. Title ~152px, H2 60–88px. A terminal period in --accent-blue (<span class="blue">.</span>) is a signature flourish.
• Quote hero — Manrope 800 at ~92px with an oversized cobalt “ mark (~220px): quote typography is the deck's hero visual.
• Kicker — 22px, 800, uppercase, letter-spacing: 0.34em, cobalt on white / white on cobalt.
• Body / lede — 400/500, 25–33px. Support copy on the white panel uses --text-dark-soft; body copy on the cobalt panel stays full --text-light for WCAG AA contrast (the soft light alpha is reserved for bold uppercase chrome: marks, hints, separators).
• Marks — 19px, 800, uppercase, letter-spacing: 0.22em.
• Never substitute Inter, Roboto, Arial, serifs, or any second typeface.

Locked layout system — vertical split panels

Every slide is the same shell:

<section class="slide s-<master>">
  <div class="split">
    <div class="panel panel-white panel-pad"> … </div>
    <div class="edge-bar"></div>            <!-- 14px #0a0a0a accent bar on the panel seam -->
    <div class="panel panel-blue panel-pad"> … </div>
  </div>
  <div class="mark mark-tl dark"><span class="chip"></span>Brand</div>
  <div class="mark mark-tr dark"><span class="soft">Section</span></div>
  <div class="mark mark-bl light"><span class="soft">Deck label</span></div>
  <div class="mark mark-br light">NN / NN</div>
</section>

• White above, cobalt #4361ee below — always. Vary only the split ratio per master; never side-by-side splits, never blue-over-white.
• Edge bar (.edge-bar, 14px, --bg-dark) sits on the seam of every slide; use .edge-bar.light (white) only when a slide reads as cobalt-dominant and needs the inverse.
• Brand marks in corners are the chrome (no breadcrumbs, no baseline rule): top-left cobalt chip (16px square) + wordmark; top-right section label; bottom-left deck label; bottom-right NN / NN page mark. Marks over the white panel use .dark, marks over the cobalt panel use .light.
• Horizontal padding is --slide-pad-x (110px) on both panels; spacing stays confident and restrained — generous margins, no cramming.

Master pages (compose decks from these; all present in the seed)

Master	Split	Content
s-title	50/50	Kicker + giant statement title on white; lede + meta row on blue
s-agenda	348px / rest	H2 on white; numbered hairline rows (--line-light) on blue with idx + hint
s-divider	150px / rest	Empty white strip; giant outlined number (-webkit-text-stroke: 3px var(--bg-white)) + label on cobalt
s-bullets	deep / 240px	Kicker + H2 + ≤3 tick points (cobalt-bordered .tick with inline-SVG check) on white; one bold takeaway on blue
s-stat	deep / 300px	Oversized cobalt number (~400px, 800) on white; label + note on blue
s-quote	deep / 220px	Cobalt “ + 92px statement quote on white; attribution on blue
s-compare	50/50	The split IS the contrast: "their way" on white vs "our way" on cobalt, dash-topped list items
s-grid	300px / rest	H2 on white; 2×2 .gcard grid (2px --line-light borders) on cobalt
s-chart	deep / 200px	Pure-CSS bar chart on white: cobalt bars (.solid fill or --blue-soft + cobalt border), scaleY(0)→1 entrance; takeaway on blue
s-close	150px / rest	Cobalt-dominant statement ("Let's make something electric.") + inline-SVG contact links

Fixed 16:9 stage — NON-NEGOTIABLE scaling system

• Author every slide on a fixed 1920×1080 canvas: .deck-viewport (fills the window) wraps .deck-stage (1920×1080, transform-origin: 0 0).
• JavaScript scales the whole stage uniformly: factor = min(innerWidth/1920, innerHeight/1080), then translate(x, y) scale(factor) to center with letterbox/pillarbox; re-run on resize.
• Never reflow content per device; no responsive breakpoints inside slides; all measurements are fixed px at design size.
• Keep the FULL viewport-base.css block from the seed (stage, slide stacking, print styles, prefers-reduced-motion).
• Slide switching toggles .active/.visible (visibility/opacity/pointer-events) — never display: none.
• Navigation runtime (keep the seed's SlidePresentation controller verbatim): ←/→/↑/↓/Space/PageUp/PageDown/Home/End, debounced wheel (~650ms), touch swipe (≥40px), #/<index> hash routing with deep-link restore, page counter pill in .deck-controls fixed outside the scaled stage.

Motion

• Entrances only: .reveal elements transition when the slide gains .visible; stagger via transition-delay in ~0.1s steps.
• One signature easing: cubic-bezier(0.16, 1, 0.3, 1). Animate only transform and opacity. Chart bars enter via scaleY.
• prefers-reduced-motion support is mandatory (in the base CSS).

Output contract

• Single self-contained .html: all CSS/JS inline, zero build, zero external JS, no CDN scripts. Google Fonts link for Manrope is the only external reference.
• Icons are inline SVG (stroke #4361ee on white, #ffffff on cobalt). Charts are pure CSS. No remote images.
• No scrolling, no overflow: split content into more slides instead of shrinking type. Low-density speaker-led decks: one idea per slide, 1–3 bullets. High-density reading-first decks: structured grids, max 4–6 cards.
• Comment every section: /* === SECTION NAME === */. Never negate CSS functions directly (-clamp() is silently ignored) — use calc(-1 * clamp(...)).
