/**
 * Legal Communications Tools — shared UI component primitives.

 * Plugin-wide, un-scoped CSS for components that any module can reuse.

 * Modules opt in by declaring this stylesheet as a dependency of their

 * here.
 *
 * Naming convention: `.lct-<component>` for primitives, `.lct-<component>-<state>`
