Stitched Full Page Capture

Capture or repair reliable full-page screenshots for lazy-loaded, scroll-animated, Framer, WebGL/canvas, or reveal-heavy web pages. Use when full-page screenshots are blank, gray, white, sparse, show a tiny content strip, disagree with a working scroll video, or when article evidence/section crops must be derived from a trustworthy full-page image.

Scenario: Repair a full-page screenshot that contains blank animated sections.
Example input
# Capture problem

The live page scrolls correctly, but the full-page capture has two gray sections.
Both sections lazy-load images and start their reveal animation only after entering view.
Expected output
# Capture repair

- walked the page viewport by viewport
- waited for lazy media and reveal completion
- captured overlapping segments
- stitched against stable landmarks
- verified the final image against a real scroll recording
