/* ═══════════════════════════════════════════════════════════════
   TABTRICKLE — v2 design system
   Derived from the Tab a0 keycap logo kit (see docs/brand-asset-inventory.md).

   Colour rule that generates this entire layout:
     lime #BCEE09 on ink   = 14.5:1  → accent on dark surfaces
     lime #BCEE09 on white =  1.37:1 → NEVER lime type on light
     ink on lime fill      = 14.5:1  → primary buttons
   So: ink sections carry the lime; light sections carry ink type and use
   lime only as a solid fill behind dark text.
