/* Cold Opens — "tonight's listings".
   Dark: a late-night broadcast (warm black, cream ink, the amber of an on-air lamp).
   Light: the printed TV guide (newsprint, black ink, listings red).
   Type: Instrument Serif for titles (the voice of the shows), IBM Plex Mono for codes and labels
   (the voice of the listing), IBM Plex Sans for interface text. All self-hosted (OFL).
   Every colour pair here is contrast-tested in tests/unit/theme.test.js. */
