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>

// The host keyboard as the UI's external keyboard. The web board declares HAS_CARDKB

// (an ASCII keyboard that can come and go), so the touch UI's own external-keyboard

// path does the work: typing into the bound field, Enter to send, Esc = Back, arrows
|

// drive the focus group (CAP_KEYPAD_NAV). It counts as "connected" from the first

// physical key press, so a touch-only visitor keeps the on-screen keyboard.

// Limitation of that path: ASCII only (CardKB codes); other scripts use the
