Type Alias PathLeaves<T>

PathLeaves: T extends object
    ? {
        [K in keyof T]-?: T[K] extends undefined
            ? never
            : `${Exclude<K, symbol>}${PathLeaves<T[K]> extends never
                ? ""
                : `.${PathLeaves<T[K]>}`}`
    }[keyof T]
    : never

Generates only the leaf paths (final values) for an object type.

Useful for validation systems and data mapping where you only care about paths that lead to actual values, not intermediate objects.
