/* ===================================================================
   blog.css — Shell und Artikel-Typografie des BeKlaro-Blogs
   ===================================================================
   Einbindung IMMER nach beklaro.css (Tokens/Fonts/Reset kommen von dort).

   Abschnitt 1 (Seiten-Shell) ist WÖRTLICH aus preise.html übernommen,
   damit der Blog exakt wie der Rest der Seite aussieht — Nav, Hamburger-
   Menü, Footer, Buttons. Nicht neu erfunden, sondern kopiert.
   Abschnitt 2 ist blogspezifisch und neu.

   Ampel-Farben (--green/--amber/--red) sind ausschließlich echten
   Status-/Compliance-Anzeigen vorbehalten. Im Blog werden sie NICHT
   dekorativ eingesetzt — Akzente laufen über --navy.
