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