/**
 * Toast — semantic toast message (350px filled surface, 8px radius).
 *
 * Matches the Figma `toast` component (page "Messaging (Notification)"):
 * a leading icon, an optional bold heading, the message body (default slot),
 * an optional inline link/action group (`actions` slot) and a trailing close
 * button (shown by default — `closable` defaults to `true`).
 *
 * Placement, vertical stacking and auto-dismiss are the consumer's
 * responsibility — this atom is just the surface. Its entrance animation
 * (slide-down + fade-in) plays once on mount; closing it fades it out in
 * place before `mudClose` fires (Figma Behavior › dismissal).
 *
 * Pattern B (atom-display + interactive close): the close affordance lives
 * inside shadow DOM so it participates in tab order with a real
 * `button` role. The body itself is not interactive.
 *
 * `variant` selects the semantic color family — `info`, `warning`, `success`,
 * or `error` — each a filled toast surface with its own leading icon.
 *
 * Live-region routing:
 * - `info` / `success` → `role="status"` + `aria-live="polite"`
 * - `warning` / `error` → `role="alert"` + `aria-live="assertive"`
 *
 * Set the native `aria-label` attribute on the host for an explicit accessible
 * name when the body content alone is not descriptive enough.
 *
 * @element mud-toast
 *
 * @slot - (default) The message body. Plain text or rich inline content.
 * @slot icon-start - Optional override for the leading icon. When supplied,
 *                    suppresses both the `iconName` prop and the per-variant
 *                    default icon.
 * @slot actions - Optional inline action group (typically `mud-button` or
 *                 `mud-link`). Renders as its own line below the heading/body
 *                 stack (Figma `toast` `w/ heading: link` variant).
