Hello guys! I am a new to using ory and I have a few questions and concerns. 1. How does ory kratos work in an environment that has specific needs when storing user registration data? a. Adding onto this, there is certain information and things I need to store alongside the user, how would this work with ory? 2. How does ory hold up in a production environment? Will it be able to handle massive amounts of login/registration requests if need be? 3. How easy is it to setup ory for a production environment? 4. Is there an easy way to setup rules for emails as well? As I have very specific requirements for the emails that can be used for registration
