/* /record — the claim-record front door.
   Instrument-lab system, ported from the Landing v2 design bundle. Tokens are
   --rc-* scoped so they cannot collide with theme.css or book.css's --bk-*.
   Light mode keys off the same [data-theme] attribute partials/theme-init
   manages. No webfonts: deliberate system stack, so there is no silent
   fallback and no external request under CSP.

   ⚑ DOCTRINE THIS FILE ENFORCES VISUALLY (BOOK_INTEGRATION.md):
   - a MISS renders at identical weight to a HIT; --rc-hit/--rc-miss are
     equal-lightness pairs, never a green win and a muted grey loss
   - waiting/absent states are copper and slate, never error red
   - no glow, gradient, or animation loop anywhere near a number
   - the only motion verbs are settle and print-in, both reduced-motion safe */
