/* Navbar toggler (hamburger) on small screens.
   The navbar-light default toggler icon is a dark SVG meant for light
   backgrounds; against the dark navbar surface it (and its faint dark border)
   are invisible, so the collapsed menu — Plotboek/Admin links, theme toggle,
   and login/logout — appears to be missing on mobile. Give the toggler a
   visible border and focus ring in both themes, and a light icon in dark mode. */
