Centred at the bottom for eight seconds, the Undo toast sat over the events moving up into the gap an ignored or completed row left. It now sits in the bottom-right corner, lasts four seconds, and has an OK that closes it without undoing. On a phone there is no side to clear and the bottom is where an event's page ends, so it goes to the top, over the header. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
