   Bondom V2 storefront design system
   --------------------------------------------------------------------------
   One stylesheet, no build step, dark only. Sections:
     1. Tokens            6. Header, tab bar, footer
     2. Base              7. Commerce components (cards, promos, buy panel)
     3. Layout            8. Flows (checkout, orders, wallet, SMS, legal)
     4. Controls          9. KHQR card (geometry verified, do not tweak)
     5. Feedback         10. Responsive, motion, print

   Identity
   --------
   Bondom sells digital goods paid by bank QR, so the visual language is
   the receipt: dashed perforation rules, tabular figures, small mono
   labels for facts. Green marks action and live state only; surfaces stay
   neutral and are separated by hairlines rather than glow. The lime
   accent is reserved for one job: confirming that something succeeded.
