+### GET /tips/:tip_id/content
+
+Get the message content associated with a `TipSent` event. The first request
+fetches the event's IPFS content hash through the configured Pinata gateway and
+caches the result permanently in `tip_content`. Cached content is not fetched
+again. Content is limited to 500 characters when stored.

+- **Auth:** None
+- **Response:** `200 OK` when content is fetched or unavailable; `404 Not Found`
+  when the tip does not exist

+If the IPFS request times out after 5 seconds (or the gateway cannot provide
+the content), `content` is `null` and `content_unavailable` is `true`. Failed
