How would you use PaC to introduce pipeline parallelism?

It tests whether you can restructure a sequential Jenkinsfile into independent concurrent stages using Declarative parallel syntax. First, identify independent work like unit tests, linting, and security scans. Second, place them in a parallel block with stage-level agents to distribute load across the environment. Third, apply the matrix directive for multi-axis suites such as cross-browser testing. Fourth, keep all changes in a version-controlled Jenkinsfile for auditability.
