Announces Wasm-Bindgen-Ray, a crate that lets websys-style DOM and canvas APIs run from native Rust threads (Tokio) by reimplementing the wasm-bindgen macro ABI for webviews and other JS engines (Node, Bun, QuickJS). Implements a request-response bridge plus an XMLHttpRequest-based lock to cope with re-entrant JavaScript and provide cross-runtime borrow checking. Demonstrates unmodified Yew/Leptos apps and canvas drawing working natively with modest overhead; claims compatibility with existing wasm-bindgen ecosystem.
