New board variant compiling the unmodified MyMesh/UITask/DataStore app logic against real mesh::Radio/MainBoard/RTCClock/RNG interfaces, for running the actual firmware outside embedded hardware: - Native (plain g++, platform = native): ASCII-art display over stdout, stdin-driven input, local-disk-backed DataStore/IdentityStore. - Emscripten/WASM (variants/sim/build_wasm.sh, since PlatformIO's native platform force-overrides any CC/CXX toolchain override back to system clang++): canvas-backed display, IDBFS-backed persistence across page reloads, JS-callable input via sim_enqueue_key(), emscripten_set_main_loop. Real rweather/Crypto (AES128/SHA256/Ed25519) vendored unmodified and proven working on both targets. variants/sim/web/index.html is a bare verification harness, not the polished website embed.
