       or transform to .site-header (a common dark-theme move), the header
       becomes the containing block for this panel, and top + bottom then
       resolve against the header instead of the viewport. A 64px offset inside
       a 64px box leaves the content box at zero, so the menu opens showing only
       its own padding. Setting the height explicitly makes that impossible
       whether or not the blur is ever added. vh first, dvh second so dvh wins
       where supported and mobile browser chrome cannot clip the panel. */
