+- **Mute broadcast result (2026-09-18):** the profile page now shows a
+  broadcast result modal after a mute (`0x6d16`) or unmute (`0x6d17`) is
+  broadcast. On success the modal shows a broadcast success message, the mute
+  transaction id, and a `bch.loping.net` block-explorer link that opens in a
+  new tab; on failure it shows the real broadcast error message. A successful
+  mute still flips the button to Unmute and a successful unmute flips it back
+  to Mute; a failed broadcast leaves the button unchanged. The modal stays open
+  until dismissed, and dismissing it closes the modal without navigating. Pure
+  result state lives in `ProfilePage` (`lastMuteResult`,
+  `getMuteBroadcastMessage`, `getMuteResultError`, `dismissMuteResult`); the
+  presentational `MuteResult` and shared `ExplorerTxLink` components are plain
+  `React.createElement`, shared with the Node acceptance adapter
+  (`acceptance/lib/render-mute-result.js`). Client-only. Spec:
+  `psf-memo-client/specs/mute-broadcast-result.feature`. Merged to `master` at
