How to test/reproduce

• Start the app
• Open a meeting page
• Ensure the styling of the meeting page is as expected
• Ensure the styles of an editor page have not changed

Challenges/uncertainties

Unsure why we were loading the editor styles after the app styles, but this approach seems safer to me.

Checks PR readiness

• UI: works on smaller screen sizes
• UI: feedback for any loading/error states
• Check cancel/go-back flows
• Check database state correct when deleting/updating (especially regarding relationships)
• changelog
• npm lint
• no new deprecations
