- CardAnim component lerps cards from old to new position on every move - card_plugin now adds CardAnim instead of teleporting cards on state change - Snap-back on invalid drag reuses the same mechanism (StateChangedEvent) - Win cascade flies all 52 cards off-screen with staggered delay on GameWonEvent - Achievement toast scaffold wired to AchievementUnlockedEvent (Phase 5 content) - Fix input_plugin test: click Queen's visible strip, not geometric centre Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
