Summary
Works primarily in WebCore rendering, with a concentration in CSS view transitions — snapshot capture, transition group keyframes across dynamic stylesheet mutation, repaint on dynamic `view-transition-name` changes — alongside a steady stream of layout-test maintenance (deflaking, fuzzy-annotation tuning, making repaint tests runnable outside WebKitTestRunner and under Site Isolation). No commits in this window are classified as security fixes or hardening; the work is correctness and test-infrastructure oriented rather than defensive. The view-transitions correctness bugs do touch state that outlives a navigation — render-blocked documents being revealed after navigating away, and running transition groups surviving stylesheet mutation — which is the kind of lifetime mismatch worth reading closely even when the fix was filed as a rendering bug.
