twin-wasm.sh

Overview

Build the web twin's firmware: modules/woz_uwb + the tests/host shim compiled to WASM (Emscripten), driven by web-twin/twin_glue.c. Output is a single self-contained web-twin/twin.js (MODULARIZE + SINGLE_FILE: the .wasm rides embedded, so the page keeps working from file:// and the site copy stays a flat file pair). The compile is path-prefix-mapped for reproducibility: the same emsdk version must produce a byte-identical twin.js on any machine, which is what lets CI rebuild and diff it as a staleness gate.
