The touch UI (src/ui-touch, unmodified apart from WADA_WEB board guards) builds for macOS with CMake and runs in an SDL2 window: a compat layer for the Arduino/ESP-IDF/FreeRTOS surface, a MyMesh stand-in with a MeshBackend interface (DemoBackend now), and the web board's SDL display/touch/keyboard drivers. WEB_BUILD.md follows. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
