+ * /u/[handle]/posts — public Instagram-style scroll feed.
+ *
+ * Server shell so we can export `generateMetadata` for OG previews on
+ * direct shares of this URL. We re-use the same profile-OG metadata as
+ * /u/[handle] — the post anchor (#post-<id>) that may be appended to
+ * the URL is a client-side fragment and never reaches server-rendered
+ * metadata, so we can't surface post-level OG here.
+ *
+ * (Post-level OG cards still work via the SharePostSheet → short link
+ * → /share/[code] route, which DOES see the hash and dispatches to
+ * `ogForPost` in share-og.ts.)
