/**
 * Banner — full-width, top-of-page system message.
 *
 * A persistent, non-contextual notification that spans the width of its
 * container and informs users of important system-wide events (scheduled
 * maintenance, outages, announcements). Draws attention without blocking
 * interaction; remains visible until dismissed or resolved.
 *
 * Pattern B (atom-display + interactive close): the optional close affordance
 * lives in shadow DOM with a real `button` role. The body is not interactive
 * apart from the optional inline link.
 *
 * `variant` selects the semantic color family — `info`, `warning`, or `error`
 * (Figma exposes no `success` for banners). `emphasis` selects the surface
 * treatment — `subtle` (tinted) or `strong` (filled, on-color foreground).
 *
 * Live-region routing follows WCAG status/alert conventions:
 * - `info` → `role="status"` + `aria-live="polite"`
 * - `warning` / `error` → `role="alert"` + `aria-live="assertive"`
 *
 * @element mud-banner
 *
 * @slot - (default) The banner message. 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.
