   Three columns (30 / 40 / 30). All interaction is CSS-only: a hidden
   checkbox (#rec) is the "recording" state. Any <label for="rec"> toggles it.
   When checked: the button flips to Stop, the mic pulses, the waveform and
   timer run, transcript lines stream in on a schedule, then the score fills.
   Unchecking resets everything to idle.
