Batch-merged 21 blog posts (8/5)

Reverted OpenSSL bump and added a guard (8/8)

Approved a bump of openssl to 4.0.2 (#1051) but it violated the repo's Gemfile invariant (must match Ruby's default gem), so I reverted it via #1063 (merged) and opened #1064 to tell Dependabot to stop proposing the same bump, then cleaned up the related branches.
