/* ============================================================
   „Studio" — alternatives, modernes Design (auswählbar).
   Aktiv nur unter html[data-design="studio"]. Umschalten über den
   Paletten-Button in der Kopfzeile (gemerkt in gerdware-design)
   oder ?design=studio / ?design=classic.

   Ziel: ruhig, luftig, klar — wie moderne SaaS-Tools, aber eigene
   Handschrift. Funktioniert mit hellem und dunklem Theme.
