Chrome-focused Capture Lab
See what a full-page capture engine has to survive.
Rotating heroes, fixed app rails, lazy catalogs, two-axis reports, growing feeds, rendered media, and accessible-review signals—tested on owned pages with declared outcomes.

Different page types expose different failure modes.
Free-engine behavior is separated from local Pro Preview evidence so the showcase does not imply features that are not publicly available.

What the evidence proves
The engine, not a mock.
The browser run loads the production capture modules inside a signed, local-only Pro Preview build and visits the owned scenario manifest in order.
Window and nested scroll positions must return to their starting points.
Carousel, animation, and video signals are recorded without claiming every state.
Automated findings require knowledgeable human review and never establish conformance.
Kapture IT Pro remains a local preview and is not available for purchase. Edge support, production licensing, billing, and publication of this Capture Lab remain outside this evidence claim.
