/* ============================================================================
   ATLAS REDESIGN — Trust Center screen styles  ·  Phase 2
   Branch: atlas-redesign-2026-06-29

   Prefix: .rd-trust-center. Tokens only (--r-*) so Calm (almanac) + Operator
   themes both work automatically. No hardcoded hex. Theme-specific selectors
   (html[data-rtheme="operator"] …) are used only where a token can't express
   the tweak (rare).

   Composition (mirrors the .dc.html isTrust slice):
     eyebrow + h1 + sub  →  4-up KPI tiles  →  1.5fr/1fr grid
       left:  Connected data sources · Audit log
       right: How Atlas earns trust · Permissions
   Trust signals (source freshness, sync status, audit entries) render only
   when a real fetcher supplies them; otherwise honest em-dash / empty states.
