- Updated settle helpers in repro tests to wait 40ms before terminal flush. - Raised process-terminal-render-harness SETTLE_MS to 67ms for 30fps timing. - Updated render-throttle mocks to advance mock time by 40ms per frame. - Added Loader component cadence test for 30fps animated repaint timing. - Added render-regressions check that non-force renders are scheduled at ~33ms.
