/* ============================================================
   Attention self-assessment -- /test (test.html) and /en/test
   (en/test.html). Ported from the preview Mati approved (Claude Artifact
   "REWRD Brain Test", 2026-10); design and copy unchanged, only the
   implementation adapted to the site: tokens come from styles.css
   (--ink0..3, --paper, --t2/--t3, --volt, --on-volt, --font-display,
   --font-body), everything is scoped under .rt so the global rules in
   styles.css (section padding, h1/h2 display face, the reset) cannot
   leak in, and the page sits under the shared fixed site header.
   Logic lives in test.js.
