   • l'encart du destinataire (Shared/EcartsEncart.razor) : .ec-enc, .ec-pli, .ec-calme.
   JETONS SEULEMENT : thèmes clair et sombre, palette active, styles Moderne / Mat / Papier suivent d'eux-mêmes. Vert = améliore,
   rouge = dégrade, gris = conforme ; la couleur porte le SENS de l'écart, jamais son signe.
