/**
 * v0.36.5.3.8 (5.3g) Phase 2 — heatmap.css
 *
 * Shared styling for Heatmap_Renderer output. Used by:
 *   - /stat/{id}/{year}/ multi-year heatmap (5.3g, MP §15.5 item 6)
 *   - /teams/ snapshot heatmap (v0.36.5.8 Class M, MP §12.4 #4)
 *   - /week/{year}/{week}/ weekly heatmap (NEW-B)
 *
 * Per master plan §12.5 cross-surface-drift risk: ALL heatmap consumers
 * share this stylesheet. Color policy lives here once.
 *
 * Color anchors taken from the existing tile/rank palette in
 * special-teams-card.css (#d4edda green family, #f8d7da red family) and
 * extended to a 5-stop quintile ramp.
