 * ## Attributes & Properties
 *
 * Component attributes and properties that can be applied to the element or by using JavaScript.
 *
 * - `disabled`: undefined
 * - `readonly`/`readOnly`: undefined
 * - `readonly`: undefined (property only)
 *
 * ## Events
 *
 * Events that will be emitted by the component.
 *
 * - `submit`: Fired when the form is submitted with its values in `detail`.
 *
 * ## Methods
 *
 * Methods that can be called to access component functionality.
 *
 * - `validate() => FormResult`: Public read contract: pull each child's live value at read time (children
 * are uncontrolled — the form does not drive their renders, AD-6).
 * - `submit() => FormResult`: Imperative submit — same path the submit button / Enter take.
