 * Samraworld Admin Header / Nav
 *
 * Two-bar layout:

 *   Menubar    — original reddish #eb7d7d with sw_dropdown menus (hover-to-open on desktop)
 *
 * Variants:

 *   .site-header--minimal     — brand + single action (Login), no menubar
 *   .site-header--mini        — brand only, smaller height
