Type Alias DeepPartial<T>

DeepPartial: T extends (...args: any[]) => unknown
? T
: T extends object ? { [K in keyof T]?: DeepPartial<T[K]> } : T

Similar to Partial<T> but applies to nested properties recursively, creating a deep optional variant of T:

Objects: All properties become optional, recursively.
Functions: Preserved as‑is (only the property itself becomes optional).
Primitives: Returned unchanged. Useful for config overrides with strong IntelliSense on nested fields and methods.

Type Parameters
