Point the Bot settings at the media tunables

   - [x] C11 preview caching: Discord-hosted image/GIF previews (WebP 320px, hash-addressed, 5 MiB
     cap, one attempt) run after every walk in both modes. Live run `...-20260916090722`:
     `previewed: 2`; thumbs served over `/api/media/<scrape>/<item>/thumb` (200).
+  - [x] C85 Point Settings → Bot at the media tunables. The tunables (Backfilling / Scraping /
+    Timers, including the backfill auto-start toggle) live in the **Bot tab** under Settings, not
+    in the Settings menu; the Settings → Bot card now says so and has an **Open Bot tab** button
+    that closes the overlay and switches to the Bot tab. This followed a report that the latest
+    scrape had no previews: the walk cached 8,570 inline and left 24,112 pending in the manual
+    backfill queue (`auto: false`), which was not running. The queue is running again (started
+    manually); the tunable toggle controls whether future walks drain on their own.
   - [x] C84 Revert the VOX preset to the NetTTS approximation. The tuned values matched the
     reference metrics but sounded far off the game voice, so SAM commit `c6b5fb7` restores pitch 3,
     rate 17, prominences 22, head size 52, lowering 40, volume 70 and reverts the tests, metadata
