Customizing Page Not Found

version: 2023.9.8

Which file/folder/UI I need to access to modify “Page Not Found” page?

I just noticed the custom.css is not injected into this page. So we’ll have to do that first before you can mess with the looks.
Also this has to be fixed Fix custom auth templates · Issue #1872 · cortezaproject/corteza · GitHub so you can style the templates as you wish.
