/* Calculette Terrasse Silvadec — styles autonomes, isolés sous .ct-widget pour
   limiter les collisions avec le CSS du site hôte.

   Charte graphique Silvadec (« Nouveaux codes de marque », juillet 2020) :
   - Bleu Nocturne  #23354B  (Pantone 533 C / RAL 5013) — couleur corporate principale
   - Vert Lichen    #91AE8F  (Pantone 7494 C / RAL 6021) — couleur corporate secondaire
   - Palette lifestyle : #E2C886, #F6A986, #BFB0A9, #C2C3D2, #D0A0A3, #8DCFD1
   - Typographie corporate : Montserrat (Bold / Regular), fallback système Arial

   Les couleurs corporate n'étant pas modifiables, les nuances foncées/claires
   utilisées ici (--ct-navy-dark, --ct-lichen-dark, tints) sont uniquement des
   dérivés fonctionnels destinés aux états (survol, texte accessible, fonds). */
