Running the real component, compiled to WebAssembly. The frame is 223 px tall, which is what this story measures at the demo width in the default type size — a narrower column or a theme that changes that size will wrap it differently.

Events and ownership

Who owns the state
CodeBlock renders state supplied by the application; it does not own durable work.
What it emits
This presentation surface adds no component-specific interaction event.
What it means
Selectable code with language context and progressive reveal.
Overflow and motion
Wide content retains context in a bounded surface; reduced motion preserves a useful state.

What the demo does and does not show

The demo above is the same Rust as the native component, compiled to WebAssembly and drawn on a WebGPU canvas — not a mock-up, a recording, or a re-implementation. What it paints is what the component paints: layout, colour from the live theme, and motion.

The live browser specimen requires WebGPU; the native component remains the authoritative runtime.

A canvas cannot stand in for the platform, so treat everything that goes through the operating system as unproven here: keyboard handling and shortcuts, screen reader semantics, text input and IME, the clipboard, file drops, and the frame rate you would get on your own GPU. Judge those in a native build. If your browser has no WebGPU, the frame says so rather than showing an empty box.
