- frontend/: simtrace-analyser PWA (index.html, sw.js, manifest.json, icons, tests/index.test.html) copied in fresh - server.py: static file serving (_STATIC_MIME, _serve_static) with path-traversal guard; injects window.SIMTRACE_EMBEDDED='1' into index.html so the PWA defaults to a relative API base - server __main__: --web-dir (default <repo>/frontend) - frontend: embedded same-origin mode; sw.js relative precache paths + cache v4; GitHub link + version-warn point at simtrace2-pysniff - version 1.1.0 everywhere (__version__, pyproject, PWA_VERSION, manifest); MIN_SERVER_VERSION stays 1.0.0 - README/scripts/.gitignore updated Tests: 107.
