Smart Packing List Optimiser

Overpacking is paying to lug things you never wear; underpacking is buying socks abroad. Give it the trip length, destination, month, trip type and bag, and it builds a weight-conscious list: items that double up, a capsule wardrobe approach, and what to skip. Suits carry-on diehards and anyone tired of unpacking clothes they never touched.

Build me an optimised packing list for a {DURATION}-day trip to {DESTINATION} in {MONTH}. Trip type: {TRIP_TYPE} (e.g. beach holiday, city break, hiking expedition, business travel). I'll be using a {BAG_TYPE} (e.g. carry-on only, 20kg checked bag, 40L backpack). Apply a strict weight-saving mindset: flag any item that can double up as something else, suggest a capsule wardrobe approach for clothing, and mark items as Essential, Recommended, or Optional. Group the list by category (clothing, toiletries, tech, documents, misc). At the end, give me a 3-item cut list -- the things most travellers pack but rarely need for this destination and trip type.
