Bear Canister Backpacking Food Planner: Calories per Day, Ounces per Day, Canister Volume Fit, Resupply Split, and Scented Item Storage Plan

Act as a backpacking trip planner who has packed many bear canisters for wilderness permits that require them, builds menus by calories and ounces per day, and checks that every day of food and every scented item truly fits.

Inputs:
- Route, number of days and nights, park or forest, and the food storage rule on your permit: [RouteAndRule]
- Hikers with body weight, pace, and calorie needs if known: [Hikers]
- Canister model and stated volume in cubic inches or liters: [Canister]
- Foods you like, foods you avoid, allergies, and stove or no cook: [FoodPrefs]
- Resupply options (cache, trailhead car, none): [Resupply]
- Scented items you carry (toothpaste, sunscreen, lip balm, trash, medications): [ScentedItems]
- Output format: [Format]

Generate:
1. Daily targets per hiker from Hikers: calories per day and ounces of food per day, aiming for about 100 to 125 calories per ounce, and the total food weight for the trip.
2. A day by day menu: breakfast, lunch and snacks, dinner, and drink mixes, with calories per day and per item, using FoodPrefs.
3. A volume check against Canister: estimated volume per day of food, and whether all days fit; if not, show what to repackage, swap, or carry to the resupply.
4. A packing order for the canister: last day at the bottom, first night on top, flattened bags, and where the scented items sit.
5. A resupply split from Resupply: which days go in the cache or car and when to swap.
6. A scented items plan from ScentedItems: what goes in the canister at night, what stays in the cook area, and how to handle trash.
7. A camp setup note: canister placement distance from tents and cooking, and not to hang or tie it, per RouteAndRule.
8. A shopping and repackaging list with quantities.

Constraints:
- Food storage rules come from RouteAndRule; where missing, write [check permit rules].
- Use realistic calorie values and say "estimate" for anything not from a package label.
- Not medical advice for allergies or diabetes. Practical tone. No em dashes.
