- BLE (ESP32): fast advertising (20-30 ms) for 30 s, then 152.5 ms, as the
nRF52 interface; the library default kept 30-60 ms forever
- Live map tiles: the WiFi drops after a minute with nothing missing
- ES8311 to standby while the I2S clocks are off, set up again before the
amp comes on
- Buzzer: no channel (DMA out of memory) waits out the samples instead of
spinning above the UI loop
- OTA: the image header check waits for its 16 bytes
- Comments: P10 is just the LED; the LCD SPI clock is 40 MHz on the wire

- genericBuzzer I2S path (BUZZER_I2S): an audio task synthesises the notes
with eased edges and keeps the DMA queue fed with silence between sounds;
ES8311 setup; amp powered through the board only around sounds
- ui-core/SoundControl.h (mode, volume, built-in sounds, melody model),
SoundNotifier moved to the Core, chanctl::melody, schema Sound page
- L2: notifications, alarm / timer ring, locator sounds, Settings > Sound,
melody editor with the playing note lit, per-chat sound, mute icon
- noteIndex() on every buzzer backend; scrolling popups past screen height
