+in the [runtime configuration](flicknote-core/src/config.rs) is an opaque cnsupa
+publishable key, not the retired JWT-shaped anon key. The value is sent through

 `apiUrl` and `gatewayUrl` can also be set in `config.json`. After changing either
 value, restart the daemon with `flicknote daemon restart`. Configure the two
 endpoint values together; setting only one is rejected.
