   RAVEN AI FUSION — Triage Inbox styles (E1)
   frontend/css/triage_inbox.css  ?v=20260611p1

   Phase 3 — PRD Epic E1. Styles for the TriageInbox PanelShell panel.

   Conventions (CLAUDE.md + tokens.css):
   - All font sizes >= --rv-fs-xs (0.78rem / ~11px floor — F-19).
   - No hardcoded z-indexes — the panel itself is positioned by PanelShell;
     any in-panel layering references --rv-z-* tokens.
   - Animations use transform / opacity only (GPU-composited).
   - Military dark theme — consumes tokens.css custom properties with
     sane fallbacks so the panel renders even before tokens.css loads.
