   Plinth — WordPress Admin Shell

   CSS naming follows BEM: pln-block, pln-block__element, pln-block--modifier.
   State classes (.active, .on, .disabled, .visible) are short because JS
   toggles them frequently. They only apply when combined with a BEM class.
   ========================================================================== */

/* --- 1. Design Tokens ---
 *
 * Override these variables in the consumer stylesheet to change colors.
 * --pln-toggle-on controls the toggle "on" color independently of the
 * brand color, so the consumer can use a different accent for toggles.
