Module ring_buffer 

Zero-allocation shared-memory ring buffer for paint commands. Zero-allocation shared-memory ring buffer for plugin paint commands.

The host and the WebAssembly guest share a single linear memory region. The guest writes raw PluginPaintCmd records followed by their payload directly into the buffer, and the host consumes them by parsing in place, avoiding any per-frame allocation or serialization overhead.

A circular command buffer backed by a shared linear memory slice.

Enums
