Potentially also go through report references and integrate those into the Handbook as well.

Complement components that are added with the team's data justice short videos: https://www.youtube.com/@PermanentCommissionRITPMaine/videos

Start by reviewing the linked Maine Data Justice Report and the current Equity Data Handbook, then compare the report references with the Handbook. Check the team's data justice short videos for related components. Done means the report is appropriately referenced and any clearly relevant references or complementary content are integrated into the Handbook.
