   hk.css – zentrales Design für ALLE HK-Tools-Seiten.
   Wird von jeder Seite VOR deren eigenem <style> geladen, damit seitenspezifische
   Feinheiten weiter greifen. Die Klassennamen sind die, die es vorher schon in
   den Einzelseiten gab (.container, .panel, .btn, .msg …) – deshalb sieht jede
   Seite ohne Markup-Änderung sofort neu aus.
   Farben/Abstände NUR hier ändern, nicht in den Einzelseiten.
