Catalog signals & Product Power & Utility Review
Document pixels, geometric perspective rectifications, and PDF byte compilations take place entirely inside browser memory via Canvas APIs. Outgoing network requests were limited to Google AdSense advertising consent beacons and Google Analytics metrics; user photographs and synthesized PDFs are never uploaded to remote servers.
Uploaded a PNG fixture to the #pick input selector, applied the white-document scan filter, and exported an 86392-byte clean PDF artifact in under 2 seconds with 92ms max task latency and zero layout shifts.
