   KI BIENE — Digitale Visitenkarte

   Bewusst eigenständige, schlanke Datei (statt main.css mit 36 KB): Die Karte
   ist eine Zielseite für NFC-Tags und QR-Codes und soll auf dem Handy sofort
   da sein. Design-Tokens und Schrift sind mit der Website identisch.

   Format: zentrierte Karte, max. 420 px — auf dem Desktop bewusst derselbe
   Handy-Look wie auf dem Telefon.
