Exporting for browsers

C# limitation

The current Web exporter rejects a build configuration containing the .NET module. This version has no confirmed standard Web export for C# projects. Changing renderer or installing another Web template does not remove this check. Do not plan a C# browser release as an available feature.

For a non-.NET configuration

1. Use a supported non-.NET build and matching Web export templates.
2. Create a Web preset. Begin with variant/thread_support=false, without a multithreaded template configuration.
3. Export into a separate directory. Host all generated files together and open the page over HTTP(S), not local file://.
4. Inspect browser Network and Console: assets must load without 404s, and the server must serve WebAssembly and related resources correctly.
5. For threads, enable variant/thread_support, use its matching template and configure cross-origin isolation. Verify actual SharedArrayBuffer availability; a preset flag alone is insufficient. PWA header settings do not replace checking the real host.

variant/extensions_support selects native-extension support; a Windows DLL does not automatically become WebAssembly. After loading, separately check audio after a user gesture, persistence and tab lifecycle restrictions.

A supported configuration should load without Console/Network errors. Source review establishes exporter configuration; browser builds, hosting headers and project execution were not tested here.
