/* Landings sectorielles d'Optimal Energy : portes d'entrée vers un quiz, publiées en minisites.
 *
 * Mêmes jetons que le quiz.css d'Alban (Connaissances n°64028, système de design OE) pour que le passage de la
 * landing au quiz se fasse sans rupture : Nobel (Jost en substitut), vert #008e37 et vert clair #64b878, encre
 * #161f28, titres en capitales 800 soulignés de vert clair, boutons pilule, halo des cartes, thème sombre.
 * Préfixe lp-, états en is-*.
 *
 * Contraste : le vert de marque sur blanc donne 4,26 ; il ne porte donc que du grand texte (boutons en 19 px
 * gras, chiffres). Les liens et les petits textes verts prennent le vert foncé #005b23 (8,3 sur blanc).
 *
 * Plan : 1. jetons · 2. base · 3. barre du haut · 4. boutons et liens · 5. titres · 6. en-tête de page ·
 * 7. sujets · 8. bandeau d'appel · 9. références · 10. façons de travailler · 11. documents · 12. contact ·
 * 13. pied · 14. écrans larges · 15. mouvement réduit et impression.
