   One consistent look for scrollbars, <select> dropdowns and checkboxes

   any component that wants a bespoke control can still override them.
   Loaded after the component styles so unstyled/native controls pick up
   the on-brand appearance, and before themes-light.css so light mode can
   re-tint them. */
