Note

Low Risk
Low risk lockfile-only dependency patch bumps; main risk is potential subtle runtime/CI behavior changes from updated gem versions.

Overview
Updates locked gem versions across Gemfile.lock and the Rails appraisal lockfiles, bumping bigdecimal from 4.1.1 to 4.1.2 and json from 2.19.3 to 2.19.4 (including updated checksums).
