/* ============================================================================
   VIBEBOX — DESIGN SYSTEM  ·  "Moss Carbon" brand
   ----------------------------------------------------------------------------
   ALL visual decisions live in this file. Layout & structure are unchanged;
   only the styling has been remapped to the brand guidelines.

   BRAND RULES baked in here:
   • Palette: Carbon / Moss / Lime / Pale Lime / Paper.
   • Lime is a DARK-SURFACE accent only — on white it disappears, so light
     surfaces stay monochrome (Carbon structure + Moss accent).
   • Type: Inter, tight tracking (-0.02em), wordmark weight 600.
