+- **Gesture and voice fields** (`gesture.js`, `voice.js`): a stroke
+  becomes a redoal gesture key through a relay (ADR-0013/0015 in the
+  redoal repo) - the input shows the key's own decode under the
+  stroke, who is at a similar shape now, and *places* with recordings
+  the visitor can pick to make that key theirs; a voice field records
+  in the browser and leaves the audio at a key. Actions may be
+  templated from the answer (`/shape/{curve.key}`) onto dynamic
+  pages, whose URL segment also fills `value: "{key}"` presets and
+  `url` resource sources; resource items with an https `audio` field
+  render a player.
+- **Announced pages** (`src/announce.rs`): a question with an
+  `event: {starts, duration, place}` window is announced in the
+  header (not the footer nav) while the window is open, becomes a
+  followup when it closes, and its record in the runtime-owned
+  `portal_events` bucket moves to `awaiting_summary` - a "post what
+  happened" task any review desk can read, published on NATS like a
+  decision. A one-minute sweeper keeps it all idempotent.
