/* FateSeal verifier SPA — self-contained styles (style-src 'self').
 *
 * UI-WAVE1 WP-U1: the Bearmark Core token contract (--bm-*) as ported by
 * Arena SSR v1 (monorepo/services/tournament/src/arena/ui/tokens-v1.ts), plus
 * the additive FateSeal verdict map (--fs-*, FATESEAL-COVERAGE.md §6). Every
 * component rule below resolves through a token: the only colour literals in
 * this file are the palette definitions in the theme blocks.
 *
 * Offline canon: no webfont declaration, no stylesheet import, no remote
 * url() — the page has no network, so the type stack is the system fallback
 * chain the token contract already names. A downloaded face would break the
 * offline guarantee, not merely the size budget. Enforced by
 * tests/site-presentation.test.ts.
 *
 * Proof Blue rule: --bm-proof appears only on verified-full surfaces and on
 * the Verify CTA. It is a verdict colour, never decoration.
