For those interested, https://crsreports.congress.gov/product/pdf/R/R47986 is a relatively approachable overview of these guidelines.

It's interesting to read the full TikTok opinion https://www.supremecourt.gov/opinions/24pdf/24-656_ca7d.pdf and search for "scrutiny" and "tailored" while referencing some of the diagrams from the overview above. It's a good case study of how different levels of scrutiny are evaluated!
