/* ============================================================
   BITCOIN ARCADE ZONE — CARD SYSTEM
   ============================================================
   SINGLE SOURCE OF TRUTH for every card on the platform.

   The design rule (locked):
     1. BIG card    — .hero-card     180×252  (160×224 mobile)
     2. SMALL card  — .feature-card  130×182  (120×168 mobile)

   That's it. Two sizes. Color = state, not size.

   Accents are driven by the --card-accent CSS variable, set
   per modifier class. Add a new state? Add a modifier here.
   Don't reach for inline styles or per-page <style> blocks.

   Requires: tokens.css loaded first.
