/**
 * /u/[handle] — public profile, Posts tab (default).
 *
 * Server shell that exists for three reasons:
 *
 *   1. Export `generateMetadata` so direct shares of this URL
 *      (https://prabhupadasays.org/u/<handle>) get a rich OG card
 *      pointing at /api/og/profile/<handle>. The layout and the body
 *      below are client components; only this file is server.
 *   2. Emit server-rendered ProfilePage/Person JSON-LD so crawlers + LLMs
 *      can resolve the profile (the layout is a client component and
 *      fetches the profile after hydration, too late for crawlers).
 *   3. Mount the client tree (<PostsGrid />), which reads the
 *      ProfileContext provided by the parent layout.
