/* Headspace Coffee — POWDER FLAT-LAY tokens (Brand Lab lock 2026-10-20 Asia/Manila)
   SUPERSEDES Conference Mauve (archived: ../archive/conference-mauve-2026-10-20/tokens.css).
   Sampled from Timothy's powder flat-lay ref (powder-flatlay-ref.jpg): mint + forest cards on white plaster powder.
   Drop-in replacement for app/public/tokens.css — SAME role names as live app; every var() keeps working.
   Apple-style type stack. Liquid Glass: .glass-card (kiosk membership card ONLY), tinted with the new forest.
   Texture: plaster / powder grain — --texture-surface → textures/paper-grain.png @ ~4–5% on large surfaces only.
   Contrast: WCAG AA 4.5:1 text / 3:1 UI. Ratios noted inline (computed Brand Lab).
   Mauve #7a5f72 is DEMOTED to optional tertiary (--brand-tertiary) — not a primary role.
   Lime #e6ff55 is BANNED everywhere (Canva legacy) — no lime token exists; do not add one.
   Highlight (Timothy lock 2026-10-20): mint #cddac8 lives on forest/dark grounds and is the status highlight (--color-highlight alias).
