/* ============================================================
   The Unknown Unknown — Site components (shared across pages)

   Depends on brand.css (design tokens + base rules).
   Load order in <head>:   brand.css  →  site.css

   Rules of the road ("Signal" light system):
   - No raw ink values here. Colour comes from brand tokens
     (--paper/--ink, --fgN, --hairline*, --surface*, --sig*, --deep,
     --olive, --cyan, --aqua, --beige). brand.css is the single source
     of truth; sync it from herstory-brand, don't fork it.
   - THE SIZE GATE, all hues: >=1rem may use --sig / --cyan;
     <1rem needs --sig-deep / --cyan-deep / --olive / --deep.
     On --deep / --olive grounds the gate INVERTS: small type goes
     brighter (--sig-bright, --aqua, --on-dark).
   - The fuchsia signal is the ask. One moment per screen — it belongs
     to the hero's outcome word, the primary button, and the one number
     being sold. Never decoration.
   - Beige grounds carry OLIVE ink only (7.2:1, no headroom to spare).
   - Violet (--violet) is heritage-only: founding material, never a
     button, link or UI state. It does not appear in this file.
   - Ink tiers on paper: --fg3 body (9.1:1), --fg4 captions (8.1:1),
     --fg5 tracked mono labels (14.4:1), --fg1/--fg2 emphasis + lead,
     --fg6 decorative only.
   - Sharp corners everywhere. Elevation = border shift + lift, never
     a shadow.
