"""Thèmes et palette de la GUI V6 (G4 — alignement maquette).

Reprend les 4 thèmes et les tokens couleur exacts de ``docs/ui_mockup_v6.html``.
customtkinter n'a pas de variables CSS : on colore chaque widget via la palette
résolue ici. Les tokens semi-transparents de la maquette (rgba) sont rendus en
hex approchés sur le fond du thème.

Import de ce module : aucun widget créé (compatible ``--self-test``).
