Companion repository for the ankurm.com article. Every transcript in docs/output/ was produced by running this project; scripts/run-all.sh regenerates all of them. Verified against Spring Boot 4.1.1 / Framework 7.0.9 / Security 7.1.1 / Micrometer 1.17.1 / kafka-clients 4.2.1 on Temurin JDK 25.0.4.1+1.
