Single response: customer profile
One response from a customer endpoint with a nested object, a list of strings, a list of orders and a null value. The order totals mix whole and decimal numbers, so they become double, and one order has an extra coupon field, so coupon becomes nullable. Root class name: CustomerProfile.

- Type fallback · avatar_url: Only null values were found, so the type is dynamic. Add a sample with a real value to get a specific type.
- Type fallback · recent_orders[].total: Both integers and decimal numbers were found, so the type is double. Integers are converted with toDouble().
- Nullable · recent_orders[].coupon: Nullable because the field is missing from 1 of 2 objects (response 1).
