// Here we choose to bind explicitly to localhost, 127.0.0.1, for security
// reasons. This binding may cause issues in some environments. For example,
// it causes connectivity issues running in WSL2, where you cannot reach the
// server when it is bound to WSL2's localhost interface. As a workaround,
// you can choose to bind to all interfaces, 0.0.0.0, instead, but be aware
// of the security implications when you expose the server on all interfaces.
