Module processor 

Runs the page’s JavaScript runtime on a dedicated background thread.

Script evaluation, DOM events, timers, and fetch settlement are processed off the UI thread. The executor maintains a private DOM mirror and sends DomSnapshots back when the DOM is mutated.

This is not a Web Worker: scripts have full window/document access. Tasks are processed FIFO, with coalescable timer wakeups.

Structs

JsProcessor

A processor that accepts JsTasks and returns the results produced by the background JS thread.

JsTaskResult

The outcome of a JS task, ready to be applied on the UI thread.

Enums

JsTask

What the background JS thread should do next.
