/*
  Daily Cast — marketing site  ·  direction: "On-air daybreak"

  Same identity as the app (app/webapp/static/style.css): a personal radio
  station that broadcasts your reading back to you at first light. Two carriers:

    1. The on-air tally — the equalizer/signal bars are the station's live
       indicator. Amber is the tally glow; the one loud colour, spent only on
       live/interactive things.
    2. First light — a single hairline amber horizon, the daybreak the product
       is named for. In the app it's a 2px line atop each card; here the hero
       makes it literal: an amber horizon across a pre-dawn indigo sky.

  Type: Fraunces (soft old-style serif) for the station's voice — wordmark and
  headings — against IBM Plex Sans for the interface and IBM Plex Mono for
  broadcast metadata (run times, dates). Self-hosted WOFF2, latin subset, OFL.
