/* Selfday-Website (#2105, neu in #2433, Konzept docs/selfday-website-konzept.md §6). Hell ist der Standard, ein dunkles Geraet bekommt dunkel
   (prefers-color-scheme, kein Skript). Alle Farbwerte stammen aus packages/ui/src/palette.css (Grund, Karte, Schrift, Akzent, Link) und
   scripts/lib/brand.mjs (Verlauf Cyan -> Blau); scripts/check-site.mjs prueft, dass jede Hex-Farbe hier in einer der beiden Quellen steht.
   Die Schrift Inter liegt unter /fonts, damit die Content-Security-Policy (default-src 'self') nichts von Dritten laden muss.
   Mobil zuerst (eine Spalte), ein Breakpoint bei 768 px. Keine Schatten ausser der Kartenkante. */
