   ATLAS REDESIGN — Briefs screen styles (Morning + End-of-day AI briefs)  ·  Phase 2
   Branch: atlas-redesign-2026-06-29

   Prefix: .rd-briefs. 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). Brief body scrolls internally; outer frame never scrolls.
