Checklist

Overview

• I have filled out all REQUIRED sections above
• PR does one thing
  • If it is hard to explain how any codes changes are related to each other then it most likely needs to be more than one PR
• Any Public API changes are explained in the PR details and conform to existing APIs

Testing

• I have included test coverage for these changes, or explained why they are not needed
• All automated tests pass, or I explained why that is not possible
• I have personally tested this on my device, or explained why that is not possible

Final pass

• Code is as readable as possible.
  • Simplify with less code, followed by splitting up code into well named functions and variables, followed by adding comments to the code.
• I have reviewed this PR myself, ensuring it meets each checklist item
  • WIP (Work In Progress) is ok, but explain what is still in progress and what you would like feedback on. Start the PR title with "WIP" to indicate this.

This is very nit but the input text fields auto-capitalize the first letter. I only noticed because I wanted to test logging in with an external ID like user but it capitalized it to User instead. Although, I think it's something that can be configured:

-    public Keyboard Keyboard { get; init; } = Keyboard.Default;
+    public Keyboard Keyboard { get; init; } = Keyboard.Plain;
