The tuner self-closes on song:play; autoplay fires it right after a song
switch, so an auto-opened tuner flashed shut ~1s later. An arrangement
switch (which never arms autoplay) instead persisted — the opposite
tester reports, and not the mic.
- New opt-in setting autoOpenOnTuningChange (tuner Settings, default OFF)
- An auto-opened tuner persists: it ignores the autoplay song:play, stray
outside-clicks, and same-screen re-emits, closing only via the new
in-panel x / Skip buttons or leaving the song. A manual open keeps the
classic click-away / play-to-close behaviour.
- Adds the panel's first in-box close (x + contextual Skip).
- All in the tuner plugin; no core app.js changes.
Default (opt-in vs opt-out) is teed up for Byron to flip one boolean.
Staged follow-ups: E1.5 = instrument-coverage smart prompting + badge
cue; E2 = holdAutoplay gate.
Tests: tests/js/tuner_auto_open.test.js (opt-in gate, persist mode,
play/click-proofing).
