/**
 * @summary Buttons help people take action, such as sending an email, sharing a
 * document, or liking a comment.
 *
 * @description
 * __Emphasis:__ Medium emphasis – For important actions that don’t distract
 * from other onscreen elements.
 *
 * __Rationale:__ Elevated buttons are essentially filled buttons with a lighter
 * background color and a shadow. To prevent shadow creep, only use them when
 * absolutely necessary, such as when the button requires visual separation from
 * a patterned background.
 *
 * __Example usages:__
 * - Reply
 * - View all
 * - Add to cart
 * - Take out of trash
 *
 * @final
 * @suppress {visibility}
