 * **Crossfade / AutoDJ:** both sides resample to the chosen rate; the output stream reopens when needed and the outgoing track rebuilds from cache so mixed 88.2 ↔ 44.1 kHz transitions no longer tear mid-fade.
 * **Gapless:** the next track chains at the blend rate and the current track realigns when the stream Hz differs, instead of falling back to a hard cut.

+* **Settings → Audio → Track transitions → AutoDJ:** choose **Auto** (content-driven overlap, up to 12 s) or **Limit** (slider 2–30 s, default 15 s when enabled) to cap how long AutoDJ may overlap tracks.
+* The cap applies to end-of-track planning, JS auto-advance, smooth skip, and Orbit transition sync; the audio engine accepts dynamic overlap overrides up to 30 s.
