/* ===================================================================
   bc.css — Blendercursus, versie 2 ("Viewport")
   Laag boven styles.css/tokens.css.

   Basis = de designtaal van de klasafspraken: Baloo 2 + Nunito,
   pastelwas, witte kaarten met een accentbalk links, gekleurde
   icoontegels, genummerde bolletjes met diepte, pilletjes.

   Eigenheid = de Blender-viewport en de filmset:
     * een perspectiefraster met rode X- en groene Y-as in elke kop
     * een navigatiegizmo (X/Y/Z) dat traag ronddraait
     * elk beeld in een camerazoeker: hoekhaken, REC, lopende tijdcode
     * UV-dambord als motief (de "Color Grid" die in elke scène zit)
     * beelden die bewegen: loep, focus op een aanwijzer, turntable,
       voor/na-schuif
