/* Lotfaden · Landingpage 18 „Andocken“
   Geschichte: KI dockt sauber an Ihre Systeme an. Danach wächst die Wirkung im Betrieb wie eine Stadt,
   am Ende zieht der Sog zum Knopf „Erstgespräch vereinbaren“.
   Einstieg: Andockmanöver (182). Mitte: Datenstadt (132), hell, Türme tragen Namen von Abläufen.
   Schluss: Schwarzes Loch (03), ruhig neben dem Knopf.
   Übergang „Schleuse“: jeder normale Abschnitt ist eine Kammer. Beim Eintritt zieht sich einmal eine orange
   Naht, dann gleiten die zwei Türhälften auseinander, danach steigen die Inhalte gestaffelt auf.
   Gestaltung wie ein Instrument: feine Linien, Zielmarken an den Ecken (wie die Klammern im Zielkreuz).
   Farben: Titan #0E1116 nur im Einstieg und Schluss, sonst hell #F2F3F5 und Weiß; ein Akzent Signalorange
   #FF6B2C (als Schrift #C2410C). Schrift: Sora. Eine Kante für die ganze Seite: --edge.
   Radien: 10 px große Flächen, 7 px Knöpfe und mittlere Flächen, 4 px kleine. */
