/*!
 * Big Brain Labs — site design system (2026-11, "Big Brain Labs 2.0").
 * ─────────────────────────────────────────────────────────────────────
 * NO BUILD STEP. Every marketing / landing page links this ONE file:
 *   <link rel="stylesheet" href="/site.css">
 * App pages (morninglab, seatlab, pdflab, …) do NOT load it — apps keep
 * their own styles. polish.css is the OLD marketing layer; new pages do
 * not load it (the legal pages still carry it for their body copy).
 *
 * Layers:
 *   1. Tokens (brand palette — Ink / Blue / Mint / Gold / Cream)
 *   2. Base + typography + focus
 *   3. Layout helpers
 *   4. Shared chrome: skip link, .site-nav, .site-footer
 *   5. Components: buttons, badges, cards, tiles, hero, screenshot
 *      frames, feature rows, steps, pricing, FAQ, forms, callouts,
 *      directory, product page, doc (legal) pages
 *   6. Motion (all gated on prefers-reduced-motion: no-preference)
 *   7. Print
 * ─────────────────────────────────────────────────────────────────────
