Module selectors 

Selector-engine injection and element resolution.

The engine JS (INJECTED_SCRIPT) is registered on self.__pwcdpInjected and exposes querySelectorAll(root, selector), querySelector, and elementState(el). Resolution here goes through Runtime.callFunctionOn and returns CDP RemoteObjectIds; we resolve a single node at a time to avoid materializing (and leaking) handles for every match.

Constants

INJECTED_SCRIPT

The injected selector-engine bundle, embedded at compile time.

Functions

count

Count elements matching selector in the given execution context.

element_at

Resolve a single element (by index) to its RemoteObjectId, or None if no element exists at that index.
