Interface JxlDecoderOptions

Convenience for wasmInit.threads — opt into multithreaded decode on a cross-origin-isolated page (falls back to single-thread otherwise). See WasmHostInit.threads. Example: new JxlDecoder({ threads: 'auto' }).

wasm host initialization — where to load/serve the decoder .wasm from and the threading mode; see WasmHostInit. The wasm asset precedence (explicit wasmBytes/wasmUrl → configure({ wasmBaseUrl }) → build default) is documented once on core's BitruviusConfig.
