   STEP Agentic AI Repository — scoped stylesheet
   ------------------------------------------------------------
   EVERY rule is scoped under `.step-repo-app`. Nothing here may
   style bare `body`, `*`, `html`, or generic theme elements —
   this file is loaded inside a host WordPress theme (GMU CARE)
   and MUST NOT leak into the surrounding page.

   Rules:
   - No global element selectors (body, *, h1, a, button …) at the
     top level. Element rules must be prefixed: `.step-repo-app h2`.
   - CSS custom properties are declared on `.step-repo-app`, not
     on `:root`, so they don't override theme tokens.
   - If you add a selector, it starts with `.step-repo-app`.
   The build test (tests/) enforces this automatically.
