- Pace dropdown REMOVED from Phrase setup — replaced by a 'Sync to exercise' checkbox in the Metronome widget (analog to 'Auto' in single-note modes). pace is derived from the checkbox (checked = tempo, unchecked = step). - Preview clicks now registered in PREVIEW_GROUP: stopping/abandoning a preview cancels its scheduled clicks — no more parallel ghost metronomes after preview->stop->next exercise. - Chord pool replaces the chord dropdown entirely (single chord AND sequences): togglable degree list, empty = all 7. - Giuliani figures corrected to NOTE sequences (p always takes the bass/ root): p-i-m, p-i-m-a, p-a-m-i, a-i-m, p-i-m-a-m-i, p-m-a-m-i-m, p-e-a-m-a-m (replaced the fingering-driven patterns that made no musical sense). - 'Limit notes' is now one bordered section like Tuner/Metronome, with a header, Clear-all link, and Strings behind a toggle (row hidden until restricted).

/**
|
||
* Metronome widget — always-visible tempo controls + pendulum.
|
||
*
|
||
* Modes:
|
||
* - Plain (single-note modes): one on/off toggle arms sound + animation.
|
||
* - Sync option (Phrase Mode): the toggle switches between
|
||
* * FREE — the metronome runs independently (own clock, starts as soon
|
||
* as toggled, with or without clicks per the sound checkbox)
|
||
* * SYNC — the metronome starts with the exercise (count-in included),
|
||
* is silent while idle, and its pendulum mirrors the run's beats.
|
||
*
|
||
* Exactly ONE sound checkbox exists (here). In sync mode it governs the
|
||
* run's click scheduler too — clicks can never double.
