Add a tri-state like/dislike toggle beside the bookmark action (signed-in only): click a reaction to set it, the other to switch, or the active one to clear — optimistic with rollback, mirroring the bookmark toggle. Seeds from the new GET /me/reactions/:id in the detail loader (non-critical: any failure degrades to an unset toggle). Unit tests cover the state machine; e2e drives set → switch → clear against the real endpoints. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
