/* news.kiserver.dedyn.io — IT-News mit Eventkalender
   Performance-first: kein Framework, keine externen Fonts/CDNs,
   keine Web-Font-Downloads (System-Font-Stack).
   CSP-kompatibel: script-src 'self'; style-src 'self' 'unsafe-inline'.
   Palette: FT.com-inspiriert (warmes Papier-Creme, dunkle Serifenschrift)
   fuer hohe Lesbarkeit im "Nachrichtenportal"-Look.
   Mobile-first responsive: Sidebar wandert per Grid-Order neben den Feed,
   auf Mobile liegt sie im Dokumentfluss UNTER den News (kein JS noetig). */
