   WEB-DESIGN-KIT · Signatur-Komponenten (marken-neutral)
   ---------------------------------------------------------------------
   Die hart erarbeitete DNA aus der Till-Weilemann-Website, herausgezogen
   und marken-neutral gemacht: die MECHANIK (Glas-Buttons, Tubelight-Nav,
   3D-Karten-Tiefe, Grain, Hell/Dunkel-Rhythmus, Mikro-Interaktionen) ist
   fest, Farben + Typo + Casing sind Regler (unten im Token-Kontrakt).

   NUTZUNG: kit.css einbinden, dann pro Marke NUR den :root-Token-Block
   ueberschreiben (Farben, Fonts, Casing). Nie die Komponenten-Mechanik
   von Null neu bauen. Siehe README.md fuer HTML-Snippets + Recoloring.
