 * Leon AI Assistant — production website widget styles (Phase 4A §27).
 * Adapted from the hardened Phase 3.1 local demo
 * (backend/app/demo_assets/assets/style.css), namespaced under
 * `.leon-widget` (instead of `:root`/`#app`) so it never leaks variables or
 * ids into the host page, and can be dropped into an existing site
 * alongside the site's own styles.
