/* MWRiddle.com
 *
 * Design language: a detective agency's archive. Case files, exhibit
 * tags, dossiers. Built from a reference the author supplied
 * (breezymystery.lovable.app) -- palette and type measured directly off
 * that page with a canvas probe, not eyeballed.
 *
 * Two colour pairs in the reference failed WCAG AA when measured:
 *   muted-on-dark   3.62:1 (needs 4.5)
 *   red-on-dark     2.77:1 (needs 4.5)
 * Both are corrected below to compliant values that keep the same hue.
 * This audience is frequently past sixty, on a phone, next to an open
 * book -- the atmosphere has to survive that, not fight it.
 *
 * Dressed everywhere except the answer form on answer.php. Someone
 * mid-puzzle wants a fast box to type a name into, not atmosphere. The
 * theatre is spent on CASE CLOSED instead, which is what gets
 * screenshotted.
 *
 *   - 19px base, nothing under 16px anywhere
 *   - self-hosted fonts, no CDN, no JavaScript, nothing fetched offsite
 *   - touch targets at least 48px
