Generate a packing list organized by category:
1. Clothing — minimum viable wardrobe with mix-and-match logic
2. Footwear — pairs needed and why each
3. Toiletries — essentials only, with TSA size notes if flying carry-on
4. Electronics — including adapters for the destination
5. Documents and money — exactly what to bring
6. Health and first-aid
7. Activity-specific gear
8. "Just in case" items worth their weight

Mark each item: ESSENTIAL / RECOMMENDED / OPTIONAL.
End with what to deliberately leave at home.
