   ANDRÉSY — l'app des Andrésiens
   DA « Le confluent » : l'eau et la lumière. Andrésy est née au
   confluent de la Seine et de l'Oise, et son blason porte encore
   la galère romaine qui y surveillait la navigation. La palette
   part de là — ardoise profonde, bleu Seine, sable de berge —
   et se réchauffe d'un corail pour ne jamais tomber dans le bleu
   froid des administrations.
   Volontairement éloignée de Dampierre (crème / vert forêt / ocre) :
   deux communes, deux identités.
   Mobile-first absolu ; desktop cappé à 460px centré.
