   8Hats Lab — site styles. CANON: Team-Space/brand/DESIGN-SYSTEM.md (rebuilt 2026-07-17).
   :root below is copied verbatim from §5 (8Hats Lab). Do not reconstruct from memory.
   Semantic rule (§2): amber = human · jade = agents. Headings = Charcoal, never jade.
   §3: exactly two backgrounds — Lab is the cool one. The old data-theme palette switcher is REMOVED
   (it produced third/fourth page grounds + dead hexes — a bug under §0/§3).
