/* ============================================================
   hero.css — embeddable animated walkthrough demo.

   Scoping strategy:
   - `.hero-demo` is the scoping wrapper. All CSS custom properties
     live on it (not :root), so embedding inside another page
     (e.g. connectionary) doesn't leak --bg/--muted/--line into the
     host page or vice versa.
   - All descendant resets (box-sizing/margin/padding) are scoped
     under `.hero-demo *` so the host page is untouched.
   - Add `.hero-demo.dark` modifier to render as a dark card. See the
     dark-theme variant block at the bottom of this file.
   ============================================================ */
