+ * index_config/updates_feed.php
+ * ─────────────────────────────────────────────────────────────────────────────
+ * Lightweight JSON endpoint consumed exclusively by the JS auto-refresh in
+ * index.php. Returns the full updates array (JS handles pagination client-side
+ * so every poll can detect new posts regardless of which page is visible).
+ *
+ * Usage:  GET index_config/updates_feed.php
+ *         GET index_config/updates_feed.php?since=<ISO-timestamp>
+ *
+ * The optional ?since= parameter lets the client ask "give me only posts newer
+ * than this timestamp" so it can detect new arrivals without comparing full
+ * arrays.
+ *
+ * Response:
+ *   {
+ *     "ok": true,
+ *     "total": <int>,          // total posts in the feed
+ *     "new_since": <int>,      // posts newer than ?since= (0 if not supplied)
+ *     "items": [ … ]           // full array, newest first
+ *   }
