/* ============================================================
   CALCULATEUR VMA (js/vma-calculator.js)

   Habillé comme le reste de l'app : cartes sur --surface à bordure
   fine, titres de carte en --fs-lg, libellés en petites capitales,
   chiffres en tabular-nums. AUCUNE couleur en dur : tout vient des
   tokens, donc le thème clair suit sans règle à part (l'ancienne
   feuille, pensée pour le seul fond sombre, devait être ré-habillée à
   coups de !important).

   Couleurs :
     · intensité (90 → 110 % VMA) : la palette des zones, --zone-2 à
       --zone-5, portée par une pastille — le texte reste en --text ;
     · niveau du test de Cooper : --lvl, posé en ligne depuis les tokens ;
     · le reste : la teinte de la course à pied (--sport-run).
