  - [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`:

+  - [x] C73 Echo on the vox voice. `aecho`'s `in_gain`/`out_gain` scale the dry signal
+    as well as the repeats, so a low echo level quieted the whole line (the classic path's
+    loudnorm hid it; the streaming path has no measurement, so vox + stream word mode just
+    went quiet and the echo disappeared). The stage now runs at unity gain and the level
+    scales the repeats, with a limiter absorbing the summed peaks. Verified with the user's
+    settings: the no-echo, mild, and strong cases keep the same voice RMS while the echo
+    tail grows with the delay. Wrapper tests pass.
  - [x] C72 Voice processing settings and the speak bypass. The TTS panel gained a **voice
    processing** block (echo cancellation, auto gain, noise cancellation, and **off while
    speaking**), stored in `preferences.voice` and applied live on save. While a TTS burst plays,
