   fcc-editorial.css — subtle editorial signature for fcc.cc pages
   ------------------------------------------------------------
   Opt-in classes that nod to The Commons editorial style without
   replacing each page's local design. Adds:

     .fcc-onair           — pulsing red dot (brand wink)
     .fcc-ticker          — date / separator chrome for the topbar
     .fcc-eyebrow         — small-caps tracking label
     .fcc-section-head    — section title with single-rule underline
     .fcc-section-head__hint — uppercase microcopy, right side

   Designed to coexist with each site's --bg / --accent tokens.
   The on-air red is a fixed brand signature, not themed.
