The BUG-930 pin spacer sat on the last assistant row, pushing its sibling .message-actions (and follow-ups / delivery card) below half a screen of empty space. Move the same min-height onto the last turn's entry (`:last-child:has(.message-assistant)`) with align-content: start so the rectification grid wrap does not stretch its rows. Hook logic unchanged. Records BUG-1043 / BUG-1044 (pre-existing, investigating) found during browser verification.
