 * Read `element.value` for form elements (input, textarea, select).

 * Sentinel returns:
 * - `Element not found: <selector>` when the selector matches nothing
 * - `Element has no value property: <selector>` when matched element is not a
 *   form control (e.g., a `<div>`)
 *
 * Returns the empty string for cleared inputs (distinguishable from the
 * "no value property" case via the sentinel).
