/* ════════════════════════════════════════════════════════════════════════════
   Pumo Cam — design system
   Matte, warm, precise. Five hues with one job each, plus three supports:
     sand        base / neutral: hairlines, fills, neutral data
     terracotta  the brand accent: primary actions, active states, highlights
     burgundy    alerts, danger, negatives (never on a terracotta component)
     olive       people, positive, success, live-OK
     brass       a material, not a paint: brushed hairlines, indicator edges,
                 focus glints, premium badges — never a flat fill or text
     cream       elevated insets · charcoal text / dark base / video stage
     paper       the app background (instead of white)
   Every other colour is a color-mix() of these. Both themes come from the
   same tokens. Layers keep the cascade explicit (no !important anywhere).
