@RachelCorsino thanks for creating this! I can confirm the page works and looks as expected. I updated the PR description preview link so it goes to the new page.

Add a minor comment about updating the date before final review/merge, otherwise LGTM.

Great work on this @RachelCorsino ! It's looking great. Kudos on the changelogs as well! I left a note to update those once this is approved to be merged but you won't have to worry about that right now.

Requesting two small changes to resolve some visual discrepancies.

todo: We'll want to update this date to the date that the PR will be merged once it's approved.

@RachelCorsino Looks really good! Thanks for taking this on.

I've added some small notes and questions below (Some of them will need to be answered by @alex-hull and @amycole501). Let me know if you have any questions.

[RachelCorsino]

All fixes have been made and PR should be ready to go now!

This PR is not passing all test due to Snyk alert issue, which as been fixed in the following PR: USWDS-Site: Updates Snyk Alerts #2751

Thanks for the quick fixes, @RachelCorsino. I found one more reference to 3.6.1 that should be updated. I've added a suggestion in the comment below.

Other than that, just waiting to hear back from the accessibility team about the 2.4.6 checklist item.

Looking good!

List "Accessibility Guidance" section

After re-reviewing, I remembered that we added the "accessibility guidance" section to the Prose component page in order to display the accessibility page callout section.

For consistency, it's probably a good idea to add it here too.

I was able to do this by creating a _components/prose/guidance/accessibility.md file with just a comment to auto-generate the section. (Commit for reference)

<!-- Comment to avoid null content so the accessibility test section populates -->
