## SINGULARITY — "Played/Unplayed" Marks and Four New Eggs
The egg navigator gains "played / unplayed" marks, alongside four brand-new easter eggs.
**【New】**
- Egg navigator "Played / Unplayed": shows all by default; filter by "played" or "unplayed"; mark any card "played" from its top-right badge, and playing an egg marks it automatically (toggle off any time); one-click "Clear all played marks"
- Mystic Arcana (light tool · divination): MBTI insight test, horoscopes, Tarot readings, plus three pixel minigames
- Drifting Thoughts (puzzle): pluck words from a cloud sea and follow association chains to the target word hidden deepest to clear the round
- Patient Zero Trace (strategy · deduction): trace the outbreak — use sampling, the epidemic curve and sequence mutation count to pinpoint the real Patient Zero
- Crossroad Tarot (action · crossing): a tarot-themed pixel cross-the-road collection — 22 upright + 22 reversed, 44 crossings in all
- Crossroad Tarot HUD upgrade: level info is unified into a clean layout that never overlaps
**【Fixed】**
- Fixed level 40 "The Mob" showing overlapping panels and being unplayable in the packaged build
