/* Clairsol : « coupe de terrain technique ».
   Un dessin d'ingénieur rassurant : papier millimétré sable, traits nets aux coins doux,
   strates de sol (prairie, terre, sable, graves) et eau claire bleu-vert qui circule dans les schémas.
   Outfit pour les titres et les repères techniques, Atkinson Hyperlegible pour un texte très lisible.
   Signature : la coupe du parcours de l'eau, ses repères numérotés et les bandes de strates. */
