When a suggestion card drifts into the mascot's corner, the kitten turns
translucent (15%), steps back 10% (standalone `scale` so it composes with
the bob animation), and lets clicks pass through to the card. It wakes
while its bubble or the picker is open, or once the corner clears.
Also adds UX_REVIEW_2026-07-27.md — the hands-on review of the live deploy
turned into implementation-ready items (repro, location, fix, acceptance).
