   Reffinet Mail – Stylesheet im Design von panel.reffinet.com
   Mobile-first: Basis = Handy (ab 320 px), dann 600 / 768 / 900 / 1024 / 1280 px.
   CSP: keine Inline-Styles, keine externen Fonts – System-Schriften.
   Animationen nur über transform/opacity, prefers-reduced-motion wird respektiert.
