09 · React build, transformed ancestor and reveal. Page 02 with the comparison build mounted. PASS: the toast is pinned to the viewport bottom, and — the reason this page exists — every list row is visible. Watch for: rows present in the DOM but stuck at opacity: 0. That is the unresolved finding in README.md: the reveal state resolves correctly and Motion's animation never runs, so nothing fades in. It has never reproduced in a real browser, only under headless automation, and this page is where to check it.
