   viz.css -- "Scroll-Visuals" in Blogartikeln und Projektseiten
   (HTML: Services/VizRenderer.cs, Animation: js/viz.js)
   Idee: Inhalte bauen sich beim Scrollen Schritt fuer Schritt auf und machen
   den Text greifbarer (Scrollytelling). Nur CSS-Transform/Opacity -> fluessig
   auch auf schwachen Geraeten. Ohne JavaScript ist alles sofort sichtbar.
