/* ═══════════════════════════════════════════════════════════════
   THE HOUSE RADIO — /sing/radio/
   Built 2026-09-06. Uses the Living House palette and type scale;
   nothing here redefines a token, it only arranges them.

   Design note: a radio page invites neon meters and bouncing bars.
   This house does not do that. The station reads as a hymn board on
   a cream wall -- a gold hairline, burgundy ink, one slow light that
   tells you it is playing. Motion is limited to that single light
   and the progress hairline, and both stop under
   prefers-reduced-motion.
