/* ==========================================================================
   Progress surface v2 (Phase 5 of Saved + Progress Rebuild)
   --------------------------------------------------------------------------
   Lifted from docs/progress-mockup.html with three strips:
     1. Removed mockup-local :root token overrides (we use design/tokens.css)
     2. Removed .pr-meta-section + tagline-picker blocks (mockup-only chrome)
     3. Removed the * { box-sizing/margin/padding } global reset

   Heat tokens (--heat-0..--heat-4) live in design/tokens.css under both
   theme blocks so any future surface can reuse them.

   Legacy design/progress.css continues to style the v1 showProgress surface
   until Phase 6 cleanup. Active when body.pr-active is set by _showProgress
   (parallel to wb-active, sv-active, ait-v2-active patterns).
