   FEDERATION OS — CORE COMPONENTS
   fed-components.css · BUILD 02 · branch federation-os-v2
   ───────────────────────────────────────────────────────────────────────────
   Reusable visual primitives for Command / Dossier / FCC / Archive /
   Research / Council. NOT attached to any production page in BUILD 02.
   Requires: fed-tokens.css, fed-base.css loaded first.

   Palette rule: every color consumes a token. Alpha variants not tokenized
   are derived via color-mix() from tokens — no duplicate hex values.

   Lighting rule (enforced across all components):
     cyan = system activity/communication · green = verification ·
     gold = Federation authority/history · red = failure/critical.
   Glow is informational, not decorative.
