/* ===========================================================================
   GRI Voice QC Data Capture — light enterprise theme, adopted from the
   team's UI mockup (GRI_Voice_QC_Capture_Team_Mockup_1.html) as the visual
   and navigation reference. Same mobile-first discipline as before: base
   rules target 320-430px phones, a 431px breakpoint adds tablet
   refinements, a 1025px breakpoint builds the full desktop layout
   (including pinning the sidebar). No horizontal scrolling at any
   supported width.

   Class/id names already used by gri-app.js and qc-grid.js are preserved
   exactly (state-pill, notice*, stage-*, context-*, orb-*, icon-btn*,
   error-banner, caption-*, qc-*) — only their colors and, where noted,
   their container changed in this pass. Everything under "shell & nav"
   and "cards / empty states" below is new, for the sidebar/topbar layout
   and the five screens still pending real-data wiring.
