Local demo page
Pointer visibility test surface
Use this page to check the bookmarklet over normal text, clickable controls, form fields, and editable content.
Mixed controls
Editable region
This paragraph is editable. The pointer highlight should hide here so text selection and caret placement remain normal.
Dense page content
Demos and reviews often move quickly between controls, explanatory text, and calls to action. The highlighter should remain visible over clickable targets without making text fields awkward to use.
The bookmarklet is intentionally temporary. Running it again should remove the overlay, style node, document classes, and event listeners.
