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. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
