/**
 * A floating action button (FAB) used to present important actions.
 *
 * @description
 * The `m3e-fab` component is a prominent, expressive UI component that represents the primary action on a screen.
 * Designed according to Material Design 3 guidelines, it supports seven visual variants, specified using the
 * `variant` attribute—`primary`, `primary-container`, `secondary`, `secondary-container`, `tertiary`, `tertiary-container`
 * and `surface`—each with dynamic elevation and adaptive color theming.
 *
 * The component is accessible by default, with ARIA roles, contrast-safe color tokens, and strong focus indicators.
 * It can be extended to display a label alongside its icon, and responds to interaction states (hover, focus, press, disabled)
 * with smooth motion transitions, elevation changes, and adaptive color theming. It can also function as a link or be
 * used to submit form data.
 *
 * Native disabled `<button>` elements cannot receive focus. This can be problematic in some cases because it can prevent you
 * from telling the user why the button is disabled. You can use the `disabled-interactive` attribute to style a `m3e-fab`
 * as disabled but allow for it to receive focus. The button will have `aria-disabled="true"` for assistive technology.
 *
 * @example
 * The following example illustrates a basic floating action button.
 * ```html
 * <m3e-fab>
 *  <m3e-icon>add</m3e-icon>
 * </m3e-fab>
 * ```
 *
 * @example
 * The next example illustrates an extended floating action button.
 * ```html
 * <m3e-fab extended>
 *  <m3e-icon>add</m3e-icon>
 *  <span slot="label">Add</span>
 * </m3e-fab>
 * ```
