/**
 * ============================================================================
 * DO NOT REDESIGN THIS BAR. THE VISUAL DESIGN IS FINAL AND OWNER-APPROVED.
 * ============================================================================
 * The bar's look (44px single-line strip, text-h6 message, 20/24px icon,
 * size="compact" CTA, ghost-icon dismiss) is DELIBERATE and has ALREADY been
 * regressed and reverted once (#1545 "redesigned" it taller/stacked; #1551
 * reverted that UI back to #1542's approved design). See the full warning in
 * `ui/announcement-bar-view.tsx`.
 *
 * A new Figma frame is NOT permission to change any of it. Do not bump the
 * height, text scale, icon size, or CTA size, and do not re-introduce a
 * stacked / full-width-CTA mobile layout. Changes here require Michael's
 * explicit written sign-off on the PR, or they get reverted. AGAIN.
 * ============================================================================
 *
 * Platform announcement bar — DUAL MODE, works with or without SSR.
 *
 * SSR mode (Next hosts, e.g. the hub): the server resolves the announcement
 * and the dismissal cookie, then passes `initialAnnouncement` (nullable).
 * The bar renders in the first HTML byte (zero layout shift, no flash for
 * dismissed users) and skips the mount fetch.
 *
 * Client-only mode (bare React apps without SSR: Vite/CRA embeds — see
 * react-embedding-example): omit `initialAnnouncement` and mount the bar
 * PROP-LESS inside an EndpointsRuntime provider; it self-fetches from the
 * provider's `announcementsUrl` (a fixed suffix under the embedder's one
 * content base). No provider → renders nothing, never fetches (silent
 * no-op). Appearance animates in (grid 0fr→1fr) so there is no hard layout
 * jump. Deliberately NO per-component URL or platform knobs: the embedder
 * is platform-agnostic — each server returns ITS OWN announcement via
 * currentPlatform(); the platform is never sent as a parameter.
 *
 * Both modes: freshness is event-driven, no polling — `useSelfFetch`'s
 * visibility revalidation re-fetches on tab refocus when the held data is
 * >60s old (matching the server cache TTL by convention); idle tabs make
 * zero requests. Dismissal cookie is the SSOT (`announcement-storage.ts`);
 * storage reads happen ONLY in effects (a render-time read would desync
 * hydration in SSR mode).
