// Interactive locator picker: highlights elements on hover and records the
// generated selector for the element the user clicks. Mirrors the behavior
// behind Playwright's `page.pickLocator()` (recorder "inspecting" mode).
// The selector is stored on `window.__fdPickedSelector`; the Rust side
// polls for it rather than relying on a cross-task exposed-function call,
// which keeps engine teardown race-free.
// Depends on window.__fd (engine.min.js) and the recorder-support highlight
// helpers being present.
