 * ICEFAM.FM live radio hero. Glassy ICE/neon treatment that matches the
 * launchpad / player design language. Two honest states toggled by app.js via
 * [data-radio-state="on|off|loading"]. The ON AIR badge and its neon pulse only
 * render in the "on" state — the endpoint has to confirm a real broadcast.
