- Gallery: thumbnails 30 to a page, built only while the screen is still (a decode held the loop and a scroll read as a tap)
- segmented(): CLICK_TRIG, so a swipe starting on a screen's tabs doesn't switch them
- Settings > Device > Home apps removed (hold an app on Home instead)
- platformio.ini: a note that the L2 has no microphone on GPIO15 (verified on hardware)

The speaker's I2S channel was only disabled when idle, which leaves MCLK
running. Its fractional divider (160 MHz / 39 1/16 = 4.096 MHz) makes a
comb of lines every 256 kHz: one at 869.632 MHz, in the EU narrow mesh
channel, lifted the LoRa noise floor from ~-102 to ~-85 dBm, and others
land near GPS L1 and BeiDou B1. The channel is now deleted and its pins
held low after each sound, and made again for the next one. Measured:
noise floor -102 dBm, outdoor first fix 87 s (was 620 s and more).
Also: TCXO at 3.0 V (the L2's part, as Meshtastic has it); GLONASS
enabled on the L76K after each power-up; begin() on a running receiver
no longer resets it (a reset threw away the acquisition in progress).

- 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

Seeed Wio Tracker L2 (ESP32-S3R8 16MB/8MB PSRAM, SX1262, NV3031B 320x240
QSPI LCD + GT911 touch + LP5814 backlight, TCA9535 expander gating every
rail, ADS1115 battery ADC, AW35615 USB-C, L76K GNSS).
Board layer ported from meshcore-dev/MeshCore PR #3381 (Hacuchino-hash),
kept at the same paths for an easy upstream merge. Differences:
- display: dropped the UIColor theme (not adopted in this fork)
- GpsTap diagnostics wrapper omitted; GNSS reads Serial1 directly
- nv3031b ODR fix dropped: LovyanGFX >= 1.2.30 (now pinned) defines
Panel_NV3031B::init_cmds itself -- the fix became a duplicate symbol
- MESH_DEBUG_PRINTLN with a non-literal format fixed (broke MESH_DEBUG builds)
- upload_speed 115200: baud is virtual on native USB; skips the switch
solo/wio-tracker-l2 adds Wio_Tracker_L2_companion_solo_bringup: ui-new
zoomed 2x, BOOT button only, no touch -- a hardware smoke test, not a
release target (deliberately not *_solo_dual, so CI doesn't publish it).
The real UI for this board will be a new LVGL frontend.
Verified on hardware: boot, display, radio, GPS, battery, BLE app link.
First boot takes tens of seconds while SPIFFS formats its 3.4 MB partition.
