Bez: Generating a browser engine from specs and tests

Bez automatically generates a web rendering engine from the web specifications, the three major browsers, and the Web Platform Tests. The system models spec text, produces candidate code, verifies it against Chromium, Firefox, and WebKit, and commits verified Rust code, enabling lightweight, update-fast engines tailored to specific feature sets. Early results show high agreement among browsers, with identified Firefox bugs and robust test coverage across WPT, WebGL, and Web Audio.
