/**
 * Test whether a form control is enabled (i.e., not disabled).
 *
 * The `disabled` property only exists on form-associated elements (button,
 * input, select, textarea, fieldset, optgroup, option). For elements where
 * `disabled` is not a property, returns the sentinel
 * `Element has no disabled property: <selector>` so callers can distinguish
 * "not a form control" from a real true/false answer.
 *
 * Returns the literal string `'true'` or `'false'`.
 *
 * Sentinel: `Element not found: <selector>` when the selector matches nothing.
