/* /receipt — the claim-record demo.
   Same instrument-lab system as /record, --rc-* tokens reused deliberately
   (one design system, not two). Additions here are --rk-* scoped.

   ⚑ DOCTRINE THIS FILE ENFORCES VISUALLY:
   - a REFUSAL is rendered at identical weight to a pass. Copper and slate,
     never error red: the machine declining to grade something is a correct
     outcome, not a fault, and colouring it as failure teaches the opposite.
   - reason codes are shown as data, in monospace, never hidden behind prose.
   - the synthetic label is part of the layout, not an afterthought overlay. */
