   PaperTrade — THÈME (refonte visuelle complète, 16/09/2026)
   --------------------------------------------------------------------------
   Rôle : porter l'identité visuelle et la structure générale. Chargé APRÈS
   styles.css et refonte.css, il redéfinit les jetons (couleurs, surfaces,
   rayons, ombres, typographie) puis la charpente : barre latérale à gauche,
   en-tête, boutons, navigation, responsive.

   Direction : bleu électrique (primaire, action, navigation active), violet
   (accent), corail (alerte / baisse), vert (hausse), fond bleu-noir profond,
   surfaces différenciées, halos discrets, univers d'exploration.
