- Default URL auto-selects wss://saul-t-mote.evthings.app/rosbridge when
page is loaded via https://, falls back to ws://100.64.0.2:9090 for
local/Tailscale access
- Clears hardcoded ws:// value from input; JS sets it from localStorage
or the detected default on first load
Companion: nginx config on Orin adds /rosbridge WebSocket reverse proxy
on port 8080 → ws://127.0.0.1:9090
