   Phone / tablet menu (the slide-out panel opened by the hamburger).
   Linked after typography.css, so it wins over the theme. Colours come from
   the site tokens in site.css (--kg-blue, --kg-blue-deep, --kg-gold, --kg-ink).
   Only visible below 1500px (the hamburger header); desktop is untouched.
