   Farben kommen zur Laufzeit aus app.js: --bg und --text setzt der Nutzer,
   --surface, --border und --muted werden daraus berechnet, damit auch helle
   Themes harmonieren. Die Werte hier sind nur die Ausgangslage, bevor das
   Skript laeuft.

   Keine Google Fonts, kein CDN - auf einer Seite mit Passworteingabe waere
   jeder Fremdhost eine Stelle, an der fremder Code mitlesen koennte. Die
   Schriftauswahl greift auf lokal installierte Schriften zurueck, sonst auf
   den System-Stack.
