   - Zombie makeover (cosmetic for workers, +20 loyalty)
   - NPC customization (requires 5+ hearts)
   - 5 saved look slots

2. LAWYER OFFICE SYSTEM (LawyerOfficeSystem.js):
   - Divorce processing (50,000g + 25% money loss)
   - Prenup system (10,000g, reduces loss to 10%)
   - Marriage counseling (5,000g, 3 tasks to save marriage)
   - Relationship crisis detection (auto-unlock at 3 hearts)
   - 28-day remarriage cooldown
   - Post-divorce quests

3. ZOMBIE MINER AUTOMATION (ZombieMinerAutomationSystem.js):
   - Hire zombie miners (5,000g each, max 10)
   - Assign to specific mine depths
   - Efficiency & loyalty mechanics (0-100%)
   - Passive resource generation (yield per hour)
   - Zombie leveling system (XP from mining)
   - Equipment upgrades (pickaxe tiers, lamps, oxygen, carts)
   - Feed zombies to restore loyalty

Total new systems: 6
Total code: 3,100+ lines
