/* Project Daylight — Radio / Briefing playback page.
   Ported from the Claude Design "Radio Page" handoff (tuner player + karaoke
   transcript), adapted to the live site: it sits inside the standard masthead
   + footer and uses the site's serif/mono, with the design's amber radio
   accent and player/transcript treatment. Drives off a real <audio> element;
   JS sets --pct (0-100%) for the needle/progress, and toggles line states. */
