Type Alias DialogResultCallback

DialogResultCallback: (
formData: PlainObject,
action: string,
) => unknown | Promise<unknown>

Result-builder for the generic dialog primitive.

Invoked at the Foundry boundary when a button is pressed. Receives the parsed form data as a plain object (the boundary owns FormDataExtended and the DOM) and the pressed button's action; its return value becomes the dialog's result. This keeps callers in the logic layer free of any Foundry/DOM code.
