   Plug'n'Dose · feuille de style
   -----------------------------------------------------------------------------
   Concept : un instrument de mesure clinique. Une typographie éditoriale
   au-dessus d'un tableau de mesure interactif, des sections en colonnes
   asymétriques, une bande nuit pour le parcours de calcul.

   Sommaire
     1. Polices auto-hébergées (aucune requête vers un tiers)
     2. Jetons de design : couleurs (clair / sombre), typographie, rythme
     3. Base, typographie
     4. Composants communs (boutons, étiquettes, puces)
     5. En-tête et navigation
     6. Héros et instrument de démonstration
     7. Section Plug'n'Dose (services, publics, équipe, réglementaire)
     8. Section Tucuxi (fiche technique, parcours, interface, modèles, preuves)
     9. Section STP (fenêtre thérapeutique, pratique, domaines)
    10. FAQ, contact, pied de page
    11. Pages secondaires (mentions légales, 404)
    12. Responsive, mouvement réduit, impression
