/*
   =========================================================================
   U:Bodigat.com — eigenständiges Navbar-Stylesheet
   Klassische horizontale Navigationsleiste mit dunklem Hintergrund
   (+ Light-Mode-Variante über [data-theme="light"] auf <html>).
   Fast nur class-scoped Regeln, damit dieses Stylesheet auf jeder Seite
   (auch fremd gestaltete Lernapps/Spiele) nur die Navbar selbst betrifft.
   Die eine bewusste Ausnahme (body padding-top) ist unten dokumentiert.

   Der Font-Import steht hier (nicht in style.css), weil fremde
   Lernapp-/Spiele-Seiten NUR dieses Stylesheet laden — ohne ihn hier würde
   die Navbar auf diesen Seiten lautlos auf die System-Schriftart zurückfallen,
   obwohl 'Arimo'/'Inconsolata' unten als font-family angegeben sind.
