/* ═══════════════════════════════════════════════════════════════════════════
   Songless Unlimited

   The interface is modelled on the faceplate of a hi-fi amplifier in a dim
   room: near-black panels with a green undertone, silkscreened labels in small
   caps, tabular numerals like a tape counter, and indicator lamps that report
   state at a glance. Depth comes from hairline borders and small shifts in
   panel lightness — no drop shadows competing for attention.

   The recurring motif is the status lamp: a coloured edge or dot that says
   correct / missed / in progress / unlit. It appears on progress rows, recap
   rows, mode buttons and calendar cells, so one visual language carries state
   across the whole site.
