/*
    Rouse Refresh mega menu (dropdown)
    Used by Views/Partials/RouseRefresh/MegaMenu-new.cshtml, inside header-new.cshtml.
    Scoped to header.rr-header .rr-mega so the old .rr-menu__dropdown styles in header-new.css are untouched.

    Figma (Mega Menu - * - XLarge, 1440, light version):
    - Panel: 24px from each side of the header, 25px below it, padding 20px, radius 24px, #E8E8E8,
      drop shadow 0 4px 10px rgba(0,0,0,.10) on panel + arrow.
    - Arrow: 35x35 triangle, radius 4, top 8px below the header, centred on the menu item.
    - Cards: gap 24px, padding 28px, radius 16px, #FFFFFF 20%, border 1px #FFFFFF 13%.
    - Card heading: 4x22 accent bar #6A59FD (radius 2), gap 12px, Noto Sans 20px / 115%, -1.5% tracking, #171245.
    - Card links: Noto Sans 16px / 115%, #171245, 10px apart, two columns 24px apart.
    - Compact (Insights): 360px wide, padding 28px, radius 16px, 24px between rows, 16px row titles.
