/* Workflow Studio styles.
   Every rule is scoped under #wfs-root and every class/id carries a "wfs-" prefix, so the same file can sit
   inside a host page without restyling it or being restyled by it.
   Layout: top bar, then a dotted-grid canvas (left) beside a Code / Preview / History panel (right);
   stacks when the studio itself is narrower than 820px (container query, not viewport). */
