OptionalwasmURL of the host-served opencv.wasm asset. Omit to use the packaged asset
beside vendor/opencv.js. Use an absolute URL when overriding so resolution
does not depend on the worker's location; no CDN is used by default.
OptionalworkerCreate a dedicated module worker running the packaged /worker entry.
Defaults to a worker resolved relative to this module. The matcher owns and
terminates it on abort/disposal; the factory must return a new worker when
called again after cancellation. Do not return a shared application worker.
Host-controlled worker and WASM asset locations for browser deployments.
