- New global celebration system: celebration-store (queue) + CelebrationOverlay
(animated: count-up XP, filling bar, level-up pop, achievement cards; plays
levelUp/award sounds; tap or auto-dismiss). Rendered in page.tsx.
- Shop: every purchase now celebrates — XP packs animate XP gain + level-up,
cosmetics show a "purchased!" pop. Newly-unlocked achievements (diffed from
the profile before/after) animate too.
- XP purchases now actually evaluate achievements: gamification.evaluateAchievements
(client) + Gamification.EvaluateAchievements (server, called in ShopBuy xp path)
unlock level milestones + grant their coins.
Verified live: buying XP took L1→L5, unlocked level_5 server-side and credited its
reward. tsc + dotnet + next build clean; images rebuilt :1500/:1505.
