 ### Please don't delete this checklist! Before submitting the PR, please make sure you do the following:
+
 - [ ] It's really useful if your PR references an issue where it is discussed ahead of time. In many cases, features are absent for a reason. For large changes, please create an RFC: https://github.com/sveltejs/rfcs
 - [ ] This message body should clearly illustrate what problems it solves.
 - [ ] Ideally, include a test that fails without this PR but passes with it.
 
 ### Tests
+
 - [ ] Run the tests with `pnpm test` and lint the project with `pnpm lint` and `pnpm check`
 
 ### Changesets
+
 - [ ] If your PR makes a change that should be noted in one or more packages' changelogs, generate a changeset by running `pnpm changeset` and following the prompts. Changesets that add features should be `minor` and those that fix bugs should be `patch`. Please prefix changeset messages with `feat:`, `fix:`, or `chore:`.
