/* decode-page overrides — palette + fonts INHERITED from /styles.css.

 * COUPLING CONTRACT — grep public/decode/ before renaming anything here:
 * depends on shared tokens --primary, --primary-dark, --ink, --grey,
 * --grey-dark, --grey-lighter; on @font-face families 'Bagel Fat One',
 * 'Source Sans 3', 'JetBrains Mono'; and (in index.html) on two woff2
 * preload paths. Rename/move any in /styles.css or /fonts and DECODE breaks
 * SILENTLY (CSS falls back to system defaults).

 * Per-card --ac = the accent (magenta=system · red=blocker · green=fix ·
 * blue/purple=auth method · orange=timing). --ac-ink (set in app.js) is its
 * WCAG-AA text shade: bright --ac for fills/borders, dark --ac-ink for text. */
