/* =============================================================================
   MEGA MENU — Blogar Theme  v2
   css/mega-menu.css

   FIX 1: .mega-mobile-toggle + .mega-mobile-panel → base rule display:none
           (trước đây chỉ ẩn trong @media ≤1199px nên bị hiện trên desktop)

   FIX 2: Panel background full-width bằng negative left/right offset
           bù trừ padding của .axil-header (var --blogar-header-padding-x)

   Positioning:
     .header-inner { position: relative } → containing block
     Panel: left/right = calc(-1 * padding) → background to full viewport width
     .mega-panel-inner: padding = same value → content stays aligned

   Load order: sau header.css
