/* ==========================================================================
   Bonjour la toile
   Parti pris : un carnet d'atelier plutôt qu'un tableau de bord. Papier
   chaud, encre, crayon de couleur, ruban gommé. Les traits sont tracés à la
   main (SVG en ligne, aucune requête réseau) : filets ondulés, cercles qui
   dépassent, soulignements au marqueur. Les cartes penchent d'un demi-degré
   et portent une ombre pleine, comme posées sur la table.
   Thème clair unique, aucune dépendance externe.
