/* ═══════════════════════════════════════════════════════════════════════════
* home.css — v0911, the HOME PAGE on CG's visual idiom (BRIEF-0911.md).
* Imported by HomePage.tsx only.
*
* Every class is `zbm-` prefixed and lives under the `.zbm` root, so nothing
* here can reach the nav, the footer, the kit, another route or the
* generated demo. Light only, on the site tokens (var(--color-*)); the few
* colours with no token (role tints, the candle, the dark close) are
* declared once on `.zbm`. Unlayered on purpose: it beats Tailwind's utility
* layer and the base layer.
*
* GRID. `.zbm-wrap` is the nav's own box — max 1180px including
* max(20px, 6vw) side padding — so every section shares the logo's left edge
* and the nav button's right edge, at every width.
*
* TYPE. Headings: Source Serif 4 with optical sizing on (the display cut at
* 56–88px). Body: Instrument Sans. Labels: JetBrains Mono, 11px, tracked,
* uppercase; section kickers carry a short amber rule.
*
* MOTION CONTRACT (HomeMotion.tsx): `.zbm-rv` fades up 12px over 500ms;
* `.zbm-graph` grows its `.zbm-bar > i` from 0 to `--w`. The hidden start
* state is armed ONLY by `.js` on (layout.tsx), so the server HTML, a
* no-JS read and `?static` captures show everything at its final state.
* HomeMotion adds `.is-in`; `--zbm-d` carries the stagger delay.
* ═══════════════════════════════════════════════════════════════════════════ */

/* ═══════════════════════════════════════════════════════════════════════════
* design.css — 0931, the design pass. Loaded LAST, after base/home/extras.
*
* What it adds, in order:
* 1. Tokens and rhythm (band height, radii, shadows, the easing)
* 2. Type scale (H1/H2 display cut, italic accent, marks, numerals)
* 3. Nav + footer (sticky blur, current-page rule, two-row footer)
* 4. Image placeholders (.ph: amber wash, id, aspect, intent; hides on load)
* 5. Section layouts (hero media overlap, split variants, cost ledger)
* 6. Motion (reveal; everything off under reduced motion)
* 7. Responsive (≤1180, ≤960, ≤640; 16px gutters at 375)
*
* HIGHLIGHT RULES (keep it premium, not loud):
* .zbm-hl italic serif, amber — the one word or clause that carries the
* meaning of a headline. One per headline.
* .zbm-mk amber highlighter wash — a phrase of consequence (free, an AI team).
* Never with .zbm-hl in the same headline
* except the startups price line.
* .zbm-num display numeral — 300+, the three prices, $0.
* kickers stay mono, tracked, with the short amber rule.
