Break skill: what it does and how to install it

What it does. Builds a scratch route that imports one real component and renders it with every applicable scenario, using fixture data and fixed container widths. It performs one browser pass, marks observed breaks under each scenario and reports them with their responsible domain skill.

When to use it. Use it to check whether a component survives worst-case content and states in isolation. It does not judge interface standards, explore alternatives or fix the component, and leaves the report page running until removal is requested.
