Build scripts, CMake/source patches, npm packaging, and a Gitea CI workflow to compile the real Visual Pinball engine (SDL3 + WebGL2 + libwinevbs for real VBScript) to WebAssembly. The patches are validated end-to-end: the patched engine boots in a real browser, loads a real .vpx table, compiles its real GLSL shaders, computes environment map radiance, initializes physics, and starts the VBScript engine, before hanging on the one deliberately-deferred piece of work (game loop rewrite around emscripten_set_main_loop), documented in the README's roadmap.
