   CoinzBack V2 — dedicated page styles
   Loaded ONLY on coinz-back.html (the canonical read + claim surface per
   CoinzBack V2 PRD §2.4 + the "Dedicated CoinzBack page" user story).

   The cadence cards deliberately share the lobby carousel's class names
   (.cb-card / .cb-build / .cb-ring / .cb-claimrow / .cb-state-chip / .cb-coin)
   so the two surfaces read identically — cross-surface consistency is a design
   requirement (2026-07-09 review). The card block below is byte-parallel with
   fun-machine.css; edit both together. Safe from collision: no lobby page loads
   THIS file, and this page does not load fun-machine.css, so the .cb-card family
   lives in exactly one stylesheet per page. Only .cb-section overlaps
   coinz-hub.css, and this file never redefines it.

   All colors are ratified tokens or allowlisted raw values. No invented palette.
