/* Le Banc Optique — DA : nuit indigo, minimaliste, un peu cartoon.
   Formes arrondies, contours épais à l'encre, ombres portées « dessinées » sans flou.
   Couleurs de sens : corail = rayons laser (comme les rayons rouges du cours), cyan = verre/lentilles,
   ambre = foyers et valeurs mesurées, menthe = réussi. Thème sombre unique, choisi pour le jeu. */
