 * @summary Buttons help people take action, such as sending an email, sharing a

 *
 * @description
 * __Emphasis:__ Medium emphasis – For important actions that don’t distract
 * from other onscreen elements.
 *
 * __Rationale:__ Filled tonal buttons have a lighter background color and
 * darker label color, making them less visually prominent than a regular,
 * filled button. They’re still used for final or unblocking actions in a flow,
 * but do so with less emphasis.
 *
 * __Example usages:__
 * - Save
 * - Confirm
 * - Done
 *
 * @final
 * @suppress {visibility}
