/* ============================================================
   CastClipper — design system
   Brand: near-black canvas, one neon-green accent (#00ff9d),
   Space Grotesk (display), Inter (body), JetBrains Mono (data).

   System rules:
   - The accent marks exactly four things: the primary action,
     interactive affordances (links/hover/focus), live/success
     state, and the one conversion surface (upgrade card).
     Everything else is neutral.
   - One radius (10px; pills only for status signifiers),
     one shadow (the active app panel), one hairline.
   - No ambient gradients, glows, or decorative framing.
   Mobile-first.
