Settings > Display > Theme: Dark / Light (NVS mc_ui/light). The colour
tokens are set once before anything is built, so a change restarts the
device. Text on an accent fill is the new ON_ACCENT (it was BG, white
in the light theme); each accent has a deeper hand-picked light variant
that reads on white and takes white text. The map's empty-tile fill and
grid and the areas' outlines follow the theme too.

WiFi starts and joins on internal RAM: ~42 KB the first time, ~25 KB after,
more for WPA. Free internal RAM had shrunk to ~20 KB after opening the map
(the tile decoder's 12 KB stack, the 32 KB I-cache, the DMA draw buffers,
UI statics), so a scan failed at once (esp_wifi_init: no memory) and a join
during a tile download timed out (AUTH_EXPIRE).
- ESP-IDF: CONFIG_SPIRAM_ALLOW_BSS_SEG_EXTERNAL_MEMORY, and the esp_timer
task stack 8 -> 4 KB (it uses ~0.4 KB). Rebuild the framework libs:
pio run -e Wio_Tracker_L2_idf_libs.
- PSRAM_BSS (EXT_RAM_BSS_ATTR) on the UI's big statics: QR codes, map
state, charts, lists. .dram0.bss 115 -> 66 KB.
- The tile decoder's and fetcher's task stacks in PSRAM.
Free internal RAM, idle: 48 -> 105 KB; WiFi up: 57 KB, 29 KB at the
lowest while downloading tiles.

A pure move: each section now sits in its own header, included where its
code was, so the order of definitions is unchanged.
