Rust wasm: Browser games!
summary
Builds a browser Breakout clone using Rust compiled to WASM with Bevy as the engine and wasm-bindgen for JS interop; compilation needs a web-specific renderer swap (WebGL) and Cargo feature flags. Native release starts ~12.1 MB, LTO+size flags drop to ~10.4 MB, and running wasm-opt brings it down to ~5.2 MB. Notes single-threaded WASM, missing WebGPU support in browsers, limited audio/gamepad support, and that the game runs in-browser after the build and bundling steps.
