            (backdrop-filter, background, border, shadow, radius, overflow),

   MAY OVERRIDE: Nothing — panels.css is a base component file.
   MUST NOT DEFINE: Hero-specific panel enhancements (owned by hero-enhanced.css),
                    homepage panel spacing overrides (owned by home.css),
                    or button styles of any kind.
