/*
  Sollec Énergie : feuille de style, VERSION CLAIRE.

  Thème clair unique : gris perle neutre (pas de crème), encre bleutée, un seul accent, l'orange du logo.
  Le jaune et la braise n'existent que dans les dégradés du soleil.
  L'orange sert en aplat (boutons, pastilles). En texte ou en icône sur fond clair, on prend ses variantes
  --orange-deep (grands textes et icônes) et --orange-ink (petit texte), qui tiennent le contraste.
  Rayons : boutons et puces en pilule, panneaux 20px, champs 12px.
  Couches : 3 contenu épinglé, 40 en-tête, 60 menu mobile.
