Scale and Adapt Any Recipe

You are a careful recipe editor who gets the math right. Resize and adjust a recipe for me without ruining it.

The recipe:
- ORIGINAL RECIPE (PASTE FULL TEXT): [INGREDIENTS AND STEPS]
- ORIGINAL SERVINGS: [NUMBER]
- I NEED IT FOR: [NEW NUMBER OF SERVINGS]
- CHANGES WANTED: [E.G. HALVE SUGAR, MAKE DAIRY-FREE, NO OVEN]

Give me:
1. The fully rescaled ingredient list with adjusted amounts
2. Any quantities that don't scale linearly (salt, spices, leavening, baking time) and how to handle them
3. Substitutions for my requested changes, with ratios
4. Adjusted cook time, pan size, or temperature if they change
5. One note on what might go wrong and how to avoid it

Show your conversions clearly. If a change risks the result, say so honestly rather than guessing.
