Recording toolbar — recording
State swap to Recording. The dot turns red and pulses (CSS keyframes,
~1.4s loop), the status label colors red, the timer ticks (02:17 here
for elapsed_seconds=137.0), and the action stack swaps to
Pause (secondary) + Stop (outline).
The pulsing dot is the primary recording-is-on signal. It's visible peripherally — even when the user has the toolbar in the corner of their eye, the motion confirms capture.
The timer formats as M:SS until the hour, then H:MM:SS. Recordings
longer than an hour are unusual but the format handles them cleanly.
