/* =====================================================================
   KLIMAFLEX — styles.css
   Statischer Auftritt, eine Domain, zwei Marken (B2B / B2C).
   ---------------------------------------------------------------------
   TOKEN-SYSTEM (Design-Methodik, Abschnitt 6)
   - COLOR: gepflegte Steel/Navy-Neutraltöne + zwei Akzentwelten:
            KÜHL (Cyan→Teal→Blau) und WARM (Amber→Coral). Bewusst
            helle UND dunkle Sektionen (kein Dauer-Dunkel = Anti-AI-Default).
   - TYPE:  Display = Sora · Body = IBM Plex Sans · Daten = IBM Plex Mono.
            Kein Inter-Default. Fluide Skala via clamp().
   - LAYOUT: editoriales, großzügiges Raster; dunkle Hero → helle Sektionen
            → dunkle Akzentbänder (Stats/Footer).
   - SIGNATURE: thermisches Strömungsfeld (Hero-Canvas) + Kühl↔Warm-Dualität,
            die sich als Verlaufslinie, Akzentwechsel (B2B kühl / B2C warm)
            und Produktwelt (Kühlen/Heizen) durch den ganzen Auftritt zieht.
   Wo ändere ich Farben? -> Hier im :root-Block.
