The triangle draw descriptor's colour fields lost their bg_ prefix and style
getters take an lv_part_t. 9.6 sizes flex containers through the layout, so
popups no longer shrink when pulled past their end: lvgl_patches.py goes.
The sim wipes its LVGL object cache when the library version changes.

- 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

One .vpk file per region in /vmap (header, sorted index of tiles and
points, then the data), read in place with the index in PSRAM; loose
{dz}/{x}/{y}.vt/.vp files still work. osm_vector.py writes packs
(--pack/--name), reads OSM PBF extracts for a box (--pbf/--bbox, via
pyosmium) and picks label languages (--lang). Map tools > Vector regions
lists the packs on the card: show one on the map, delete it. No
on-device download: packs are made with the tool.

osm_vector.py --dem adds contours from the Terrain Tiles on AWS Open Data
(SRTM, ~25 m; tools/maps/dem.py, standard library only: PNG decode,
smoothing, marching squares, line joining). Every 100 m from zoom 12,
every 20 m from zoom 15; the credit names the elevation source.

Hiking routes are stored per stretch with the waymark colours of every
route along it and drawn as side-by-side stripes on a white band (half
the route ways in the Tatra sample carry two or more routes), less
simplified; demanding / alpine paths are dotted. Named points (places,
peaks with height, huts, passes, springs, viewpoints, caves) come in
small .vp files and are placed by priority as a layer over the tiles,
clear of each other and of the map controls.

Points as zigzag varint deltas, a byte length per feature to skip it,
natural land cover simplified harder: the Tatra sample goes from 4.4 MB
to 2.3 MB, panning at z14 from ~63 to ~45 ms per tile on the L2.

tools/maps/osm_vector.py turns Overpass JSON into VT2 tiles (data zooms
10/12/14, per-feature bbox, simplified); VectorTileProvider draws them
into 256 px tiles (scanline polygons, thick lines with round joins) with
a small PSRAM cache of data files. Behind Map tools > Vector map (test),
raster where there is no vector data.

- Download an area: a frame with four corner handles on the map (kept in
world coordinates, the map pans / zooms under it); a bar gives its size,
zoom range, tile count and size, the trails switch and Get; areas on the
card are outlined
- Map tools > Map areas: the downloaded areas (map/AreaStore.h,
/sdcard/maps/areas.txt) -- show (framed, outlined), rename, fill gaps,
refresh (force re-download), trails on / off, delete (in steps, keeping
tiles another area covers)
- TileDownloader: force and per-job trails options

Waymarked Trails' transparent hiking layer, kept in /sdcard/maps-trails and
blended over the base tile at render time (Map tools > Hiking trails, NVS).
An area download fetches each tile's trails after its base tile, so
re-running an area on the card adds just the trails; with live tiles on, a
shown tile missing its trails has them fetched. Tiles without a trail are
stored as 0-byte files (no cluster on FAT).

Tiles fetched while browsing online go to /sdcard/maps-live with an
index of arrival order; past the limit (Settings > Storage, 16 MB-1 GB,
default 64 MB) the oldest are deleted a few per loop. Storage shows
their count and size and can delete them all. Downloaded maps are never
touched. Roadmap: live tiles done, second batch of user items added.

- 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

- 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)

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.
