/*
  "Peili / yö": a dark, calm mirror. Ink-blue night, silver headline, frosted
  glass cards and one cyan accent. The light theme keeps the same identity.
  Contrast (WCAG AA) is checked against --pinta-kiintea, the solid card
  fallback, and --nauha-tausta, the lightest (dark) or darkest (light) band.
  All motion lives in the prefers-reduced-motion: no-preference block at the
