Build for release

$ trunk build --release

SYNOPSIS

trunk command [--release] [options]

Trunk is a build tool for Rust WebAssembly applications that handles compilation, bundling, and serving. It compiles Rust code to WebAssembly, processes assets like CSS and JavaScript, and generates the HTML and JavaScript glue code needed to run WASM modules in the browser.
The development server provides hot reloading, automatically rebuilding and refreshing the browser when source files change. Release builds apply optimizations including WASM size reduction for production deployment.
Trunk integrates with wasm-bindgen for JavaScript interop and works with frameworks like Yew, Leptos, and Seed. Configuration is managed through a Trunk.toml file in the project root.
