- Tile fetch and OTA tasks run at idle priority: HTTPClient's read loop
only yields with delay(0), which at priority 1 starved IDLE0 until the
task watchdog reset the device (decoded from the core dump)
- A failed tile is retried once; failures in a row pause 5 s ... 60 s on
the same tile, and the download gives up only after ~5 min of nothing
- The source's last zoom level (OpenTopoMap 17, else 19, or line 3 of
source.txt) caps the download range and live tiles; past it the map
magnifies the parent tile
- OpenTopoMap's "no tile" picture is never saved, and copies saved by
earlier builds are dropped when read
- The placeholder check only runs on a fresh area and for pictures with
content: plain sea / empty land tiles are genuinely identical

- Anim.h: screens emerge from the middle (background cover fades, content
drifts 6 px), Home pages slide, popups and toasts rise and fade in
- Theme.h: accent rules (fill = primary action, dim fill = selected, text =
names/counts/modes), theme layer over the default theme, radius tokens,
accent colour picker (Settings > Display & power > LOOK, NVS mc_ui)
- Splash with the Solo and upstream versions
- Status icons in equal cells, L1-style relay marks, path window with a hop
diagram, tile download popup fits the screen (WiFi only in Settings)
- Perf: uncompressed fonts, two 120-line PSRAM buffers (~48 -> ~33 ms per
transition frame); UI_PERF_TEST harness

- Screen PIN (Settings > Display & power > Security): 4-8 digits in NVS,
keypad on the lock card after every wake and on boot, 5 misses -> 30 s pause
- Live map tiles: missing tiles at the current zoom are fetched over the saved
WiFi, written to the card and drawn; WiFi drops 30 s after leaving the map;
"Live tiles" switch in Map tools
- Firmware update (Settings > System): checks the fork's latest release,
streams the -ota.bin into the spare app slot over TLS verified with the
Arduino 3.x CA bundle, checks image magic/chip id, restarts
- Release workflow publishes *_solo_lvgl envs (merged image + -ota.bin)

- New env Wio_Tracker_L2_companion_solo_lvgl_v3 on pioarduino 55.03.312-1;
the 2.0.17 env stays until the new one passes the hardware checklist
- SerialBLEInterface: NimBLE variant (PIN pairing through encrypted,
authenticated characteristic properties; setAccessPermissions is a no-op)
- buzzer: i2s_std driver on IDF 5 (legacy driver kept for 2.0.17)
- ESPNOWRadio: IDF 5 callback signatures
- ui-lvgl: psramBuf() for trail drawing, tile cache, map marks, list rows,
keyboard maps and message metadata; internal heap back to 2.0.17 level

The map's download button fetches the visible area (overview levels up to
a chosen zoom) into /sdcard/maps from OpenTopoMap or maps/source.txt,
skipping tiles already on the card and rejecting placeholder answers.
Settings > WiFi stores the network in NVS (with scan); WiFi is on only
while a download runs. HTTP runs on a worker task on core 0; the popup
shows link, internal heap and the last TLS/HTTP error.
Internal RAM was the blocker (~13 KB free with WiFi + Bluedroid): the L2
LVGL env now allocates the_mesh in PSRAM (MESH_IN_PSRAM, static RAM
210 -> 87 KB) and mbedTLS allocates from PSRAM. Confirmed on hardware.

Map screen (Home > Map): Web-Mercator tiles from /maps/{z}/{x}/{y}.png on
the card (Meshtastic MUI layout; per-column TPK1 .pak also read), drag to
pan, +/- zoom, re-centre/follow GPS, Nearby nodes with a position as
markers opening node detail. Tiles decode one per loop pass into a
12-slot RGB565 cache in PSRAM. map/TileProvider.h is the swap point for a
later vector renderer: the screen only calls renderTile(). The tile set's
credit line comes from maps/attribution.txt.
L2 mounts the card over SDMMC 1-bit (CLK 2, CMD 3, D0 1). LVGL's lodepng
is enabled; note its LVGL patch returns an lv_draw_buf_t*, not pixels.
LVGL pool 2 MB for PNG decoding. Fonts gain map / users icons.
tools/maps/fetch_tiles.py prepares a card for an area (presets for
Poland), requires an explicit tile URL (tile.openstreetmap.org blocks
offline use) and stops on placeholder images. The LVGL sim preloads
web/maps into the L2's /sdcard and puts its GPS on Kraków.
