/* =============================================================
   Elephant — Design Tokens · "Loud Recall"
   Neo-brutalist. Hard edges, thick outlines, museum-placard labels.
   =============================================================

   How to use:
   - Layout: keep using Tailwind utility classes (flex, grid, px-, gap-).
   - Color / type / shadow / border: read from tokens below via
     Tailwind arbitrary values: `bg-[var(--bg)]`, `border-[var(--ink)]`,
     or use the component classes (.btn, .placard, .card, .input) here.
   - NEVER hardcode hex — if a color isn't here, add it here first.
