Summary
A focused skill for building plain HTML/CSS/JavaScript without frameworks. It enforces ES modules, single responsibility per file, and minimal global state. You get a workflow that demands complete runnable files, not half-done prototypes with TODOs. The author includes a verification checklist and runbook template, which is practical if you're handing off static pages or small widgets to non-framework teams. Best for quick prototypes, vanilla refactors, or when you want to ship a modal without pulling in React. It assumes you know when to stop adding abstraction and just write DOM manipulation that works.
