PR Reviewer Guidelines

• It's best to pull the branch locally and test it, rather than just looking at the code online!
• When approving a PR, provide a reason why you're approving it
  • e.g. "Approving because I tested it locally and all functionality works as expected"
  • e.g. "Approving because the change is simple and matches the Figma design"
• Don't be afraid to leave comments or ask questions, especially if you don't understand why something was done! (This is often a great time to suggest code comments or documentation updates)
• Check that all code is adequately covered by tests - if it isn't feel free to suggest the addition of tests.

Not sure if lint is failing here for something similar I had, but I manually ran something like:
pre-commit run --all-files
to fix a similar error, even though I had merged in and npm reinstalled packages after the linter/prettifier upgrade.

Edit: Just noticed this was a feature merge, not main. So maybe this does just need an update from main.

Changes look good.
