Things that make review take longer:

(remove lines that do not apply to this PR)

• Changing more than 20 files (much harder to review)
• Changing more than 5 files (a bit harder to review)
• Changes to critical code (login, dashboard, etc)
• No comments on changed files
• Tests do not pass (will get pushed back)

Things that make review faster and easier:

(check box with an x where it applies)

• I attached a screenshot of the changed part of the app working
• I added tests
• This feature is requested specifically by a player
• This will fix a bug

I want to add the static build to allow for static e2e testing as well.

• Consider adding static builds of login and signup pages as well.
