/* assets/css/navbar.css
   Gedeelde navbar: logo, tabnavigatie, hamburger-menu op mobiel.
   Canonieke versie is die van index.html (compleet met hamburger + disabled-state).
   tools/index.html had voorheen geen hamburger-collapse (nav-tabs kregen alleen een
   kleinere font-size onder 600px) — bij het delen van dit bestand is dat gelijkgetrokken:
   alle pagina's die navbar.css gebruiken krijgen nu dezelfde mobiele hamburger-UX. */
