Jenkins foundations, done right

Jenkins is everywhere and usually misconfigured. Start from CI concepts and the controller/agent split, write declarative pipelines that build and test real code, bind credentials safely, factor shared libraries, and keep the instance maintainable with plugin hygiene, config-as-code, and backups. Fifteen lessons across four sections, each ending with a self-test.
