/* biaX — /demo
 * Scoped to .page--demo. Nothing here changes a token used by another page.
 *
 * The site's --text-secondary (#3a4a7a) sits at ~2.0:1 on --bg-page. That is fine
 * for a decorative label and not fine for a table of numbers, so the demo defines
 * its own muted tones in the same palette family:
 *   --d-muted  #8b9ac4  ≈ 7.2:1
 *   --d-dim    #6b7aa8  ≈ 4.7:1
