   Reinbund — Stylesheet
   Marke: vier Quadranten, die zusammen ein B bilden. Die Form eines Viertels —
   drei gerundete Ecken, eine spitze — kehrt in Knoepfen, Bildern, Karten,
   Icons und Abschnittskanten wieder.

   Kontrastregeln (WCAG AA, geprueft):
   - Schwarz auf Weiss 21:1 — Fliesstext
   - Tiefblau #2F5688 auf Weiss 7,5:1 — Links, Nebentext
   - Blau #5083BC auf Weiss 3,9:1 — NUR grosse Schrift (ab 24 px oder 19 px fett)
   - Weiss auf Tiefblau 7,5:1 — Text auf blauen Flaechen
   - Gelb auf Tiefblau 5,6:1, Schwarz auf Gelb 15,6:1
   - Gelb auf Weiss 1,3:1 — nie als Schrift

/* ==========================================================================
   Responsive
   Drei Stufen: Handy bis 480 px, Tablet bis 768 px, Desktop ab 1024 px.
   Ab 1024 px bleibt das Layout unveraendert; alle Regeln hier greifen nur
   darunter. Dazwischen liegen zwei Feinabstufungen, die schon im Layout
   stecken: ab 1000 px bricht die Fusszeile um, ab 900 px werden die
   zwoelfspaltigen Raster einspaltig.

   Schriftgroessen skalieren ueber clamp() mit der Fensterbreite; die
   Schriftart bleibt auf allen Geraeten Figtree. Eingabefelder sind 17 px
   gross, damit iPhones beim Antippen nicht hineinzoomen.
