   Gare-moi — Signalétique urbaine
   --------------------------------------------------------------------------
   Direction : asphalte nocturne + peinture routière. Le vert de fraîcheur est
   le seul accent saturé, exactement comme sur la carte de l'app : quand il
   apparaît, il veut dire « une place, maintenant ».
   Motifs récurrents : lignes discontinues (marquage au sol), équerres d'angle
   (délimitation de place), grain d'asphalte.
   Palette alignée sur apps/mobile/src/theme/colors.ts.
