/* ==========================================================================
   pv-rotenburg.com — Variante B (site-b), eigenstaendiges Stylesheet.
   Bauplan: BAUPLAN_VARIANTE_B.md. Struktur/Dichte an pv-hersfeld.com
   (Vorlage) angelehnt, Code und Tokens komplett eigen. Kein Fremdhost,
   System-Font-Stack, fest hell (kein prefers-color-scheme).

   Radius-System (bewusst 3-stufig, dokumentiert statt zufaellig gemischt):
     --r-sm  6px  -> kleine Buttons, Progressbar-Ecken
     --r-md  8px  -> Karten, Kacheln, Boxen
     --r-lg  14px -> die zwei prominentesten CTAs (Hero-Primary, Preiskarten)
     --r-pill/--r-circle -> nur funktionale Elemente (Progressbar, Fab-Buttons)
