Long Animation Frames lab
Capability-detected, local-only, and explicitly bounded by frame count, scripts per frame, string length, timestamps at 10^15 ms, durations at one day, and the exact pretty-printed UTF-8 export bytes, including one final newline. No DOM text, user content, analytics, or network calls are collected.
Capture state
The demo blocks only after activation and is intentionally capped for diagnostic practice.
