The trigger was what felt slow, and firing on the threshold instead of on release already fixed that. Speeding up the animation on top of it was a second change to the same complaint, and not one that was asked for — the morph goes back to the shared calendar slide and fade specs, so it moves at the same pace as every other transition in the app. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
