 ## Presentation checklist
 
-- Start the local dashboard before presenting: `node dashboard/server.mjs`.
-- Open `http://127.0.0.1:4173/#overview` and close unrelated browser tabs.
+- Put both computers on the same trusted network, stop any older dashboard
+  process, and run `node dashboard/server.mjs --lan`.
+- On the demo computer, open the printed **Other devices** URL for the shared
+  Wi-Fi or Ethernet interface with `/#overview` appended. Close unrelated
+  browser tabs.
 - Use a fresh page load to confirm aggregate validation succeeds.
 - Keep a screenshot or short recording as a backup, with the sample warning
   visible.
