/* Tangerine Books — typography tokens (design-system source of truth).
 *
 * Warm Four (v3): Space Mono is the "receipt layer" — everything except
 * display type. Hobo BT is the display face for screen titles, card
 * headings, hero numerals, and the wordmark. TAN Nimbus is retired from
 * layouts (#132 deleted --tb-font-accent); the woff2 stays on disk only
 * for a possible future logo lockup (see fonts.css). All faces are
 * self-hosted (fonts.css) — no font CDN (ADR-0006).
