 * EMC Platform — base stylesheet

 *   1.  Reset / base
 *   2.  Tokens / variables
 *   3.  Typography
 *   4.  Buttons
 *   5.  Form elements
 *   6.  Alerts / flash messages
 *   7.  Login page layout
 *   8.  Site header
 *   9.  Dashboard layout (sidebar + main)
 *  10.  Sidebar navigation
 *  11.  Dashboard content helpers
 *  12.  Role badges

 *  14.  Breadcrumb
 *  15.  Card
 *  16.  Filter bar

 *  18.  Detail list
 *  19.  Misc form helpers
 *  20.  Playback group mode badge
 *  21.  Approval status badges
