The fling phase called List::tick_fling itself every 16ms, so on a 120Hz phone every second frame redrew a position already drawn -- Iris saw the benchmark scroll visibly less smoothly than her own finger, and it was the rig rather than the renderer. A real fling is advanced once per frame by UiData::tick_animations from the frame callback, so the phase now starts one the way a gesture does (fling + animate) and polls is_scrolling to know when it settled. ANIM_STEP_MS becomes POLL_MS, which is what it always was here. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
