Console stream. View console output plus JavaScript errors and unhandled promise rejections with timestamps.
DOM snapshot + search. Capture a structured DOM tree with tag, id/class hints, text preview, and a searchable path.
Page source. Read and copy the rendered document HTML in a monospaced view.
Audit deck. Quick structural and accessibility signals (headings, buttons, landmarks, language, unlabeled links, missing alt/labels) plus basic timing info.
