/*
 * Misc chrome — age gate / search / 404 (agent: gate).
 *
 * New file rather than pages.css: pages.css only loads on page templates,
 * while the age gate ships in footer.php on EVERY page — so these styles are
 * enqueued globally from functions.php ('usr-misc', after style.css).
 *
 * Gate visuals 1:1 from /tmp/usr-figma/renders/age-gate.png:
 *   backdrop rgba(19,38,107,.97) · cream card ~440px r16 · centered logo →
 *   navy H3 "Research Confirmation" → RUO paragraph (lead bold) → red pill
 *   CTA → small underlined "Exit". v2 fields follow the same rhythm.
 * Search + 404 have no renders — tokens + components from style.css and the
 * archive system (assets/css/archive.css).
