- Eigene Karten-Grafik (assets/img/map-kaiserslautern.svg) aus OpenStreetMap-Daten rund um die Merkurstraße 13, in Gelbtönen, blendet weich in den Hintergrund und läuft rechts aus dem Bild - Roter Pin mit Hahn am Restaurant, Karte 'Vor Ort essen oder abholen' mit Route planen und Anrufen - Gepunkteter Weg die Merkurstraße entlang bis zum App-Symbol 'Zuhause', Karte 'Nach Hause liefern' mit Lieferando und Uber Eats; Weg zeichnet sich beim Scrollen, der Hahn fährt mit - Handy: Kartenausschnitt mit Pin, darunter die beiden Karten mit Punktlinie - Gelbe Papierkante jetzt am Ende des Bucket-Abschnitts (Take-away schneidet die Karte ab) Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
