/*
 * The complete "industrial" design system (CSS custom properties, dark theme,
 * layout, components, responsive breakpoints) is shipped verbatim from the
 * original CMS in assets/css/bestcarbide.css and enqueued separately.
 *
 * This root stylesheet only carries the WordPress theme header (above) and
 * the small set of WordPress-specific overrides needed so core-generated
 * markup integrates cleanly with the ported design.
