- Top section aggregates the CURRENT track across all sessions (track picker
defaults to the metronome's current track, persisted via metronome.curtrack):
total time / plays / bpm range, plus a per-session comparison table so you can
watch a single track progress across days.
- Each session is now a collapsible <details>: the summary shows a friendly
timestamp ("Fri Jun 16 at 2:46 PM") with total/practiced/track-count; the note
+ per-track aggregate table + delete live in the expanded body.
