/*!
 * OIADT — feuille de styles du thème (assets/css/main.css)
 * Version 1.1 — 25 août 2026
 * ---------------------------------------------------------------------------
 * Palette, contrastes et jetons alignés sur la charte OIADT et sur le
 * livrable 3 « theme-oiadt-styles_v1.css » (10 août 2026).
 *
 *  1. Rouge de marque #EA2D2B -> #E82828 (charte) : éléments graphiques,
 *     aplats et très grands titres seulement (4,4:1 sur blanc).
 *  2. Rouge porteur #D61715 -> #B01E1E (charte), 6,9:1 : texte rouge, liens,
 *     boutons.
 *  3. Encre #141311 -> #111111 ; gris secondaire #565251 -> #595959.
 *  4. Neutres alignés : fonds #F5F2F2 / #ECE9E9, accent rosé #FBEDED,
 *     filets #E6E2E2 / #D6D0D0.
 *  5. Accessibilité : #9C9894 (2,9:1, sous le seuil WCAG 2.1 AA) remplacé
 *     par #6E6A67 (5,4:1).
 *  6. Typographie inchangée : Archivo et Inter auto-hébergées. Le livrable 3
 *     proposait une pile « Aptos » en tête ; Aptos n'existant pas en police
 *     web libre, le rendu dépendrait de la présence d'Office chez le
 *     visiteur. À trancher avec la direction.
 *  7. Logo du pied de page : cartouche blanc supprimé au profit du logo en
 *     réserve blanche à fond transparent (médiathèque, id 44).
 *
 * Classes BEM du thème conservées : les conventions du livrable 3 (dérivées
 * du prototype HTML) ne recouvrent que 11 des 99 classes en usage.
