Research direction
Start by reviewing the TypeScript tile-source entry point and how rendering and image loading currently run. Evaluate Comlink and canvas.transferControlToOffscreen for moving that work into a WebWorker; done means tile rendering and loading can optionally run off the main thread without breaking display behavior.
Written by the indexing model from the issue text.
Description
Optionally, use WebWorkers to render and load images.
Specifically, use https://github.com/GoogleChromeLabs/comlink to simplify WebWorker handling.
Consider transferring the "rendering canvas" to the offscreen worker using canvas.transferControlToOffscreen.
