   Composants réutilisables extraits de la page « Renouveler votre licence »

   Tous les composants s'appuient EXCLUSIVEMENT sur les tokens --ec-* définis
   dans ec-theme.css : aucune couleur, aucun radius, aucune ombre arbitraire.

   Objectif : donner aux pages une identité EduCycle reconnaissable sans logo,
   sans réinventer le CSS page par page. Préfixe neutre `ec-` (pas `ec-pay-`).
