   KI-Führerschein — no tool-specific CSS.

   The whole tool (layout shell included) is now built from the shared stack:
   /vendor/dv-nova/dv-nova.min.css + /assets/css/site.css.

   - Learning shell: dv-topbar + dv-sidebar (sticky on desktop, off-canvas overlay
     on mobile, driven by /vendor/dv-nova/dv-nova.min.js) + dv-nav for the module list.
   - Module/quiz headers, focal/result/cert icons: dv-icon-box badges.
   - Containers, spacing, display, centering: dv:* utilities (max-w, mx-auto, flex,
     items-/justify-center, self-center, min-h-screen, p-*, mb-*, opacity-50, hidden,
     md:hidden, …).

   Intentionally empty — keep it that way. If a one-off rule ever becomes truly
   unavoidable, prefix it `app-` (never `site-`) and colour it only via --dv-color-*
   tokens (the CSP blocks inline styles). Bump the ?v= on the <link> when you do.
