/**
 * Footer — MinderServ v4 « Liquid Glass ».
 *
 * Fond rose poudré multi-couches (gradient deep → primary + halos cream/or),
 * filets dégradés cream → or → cream sous chaque titre de colonne (signature MH),
 * newsletter capsule glass, boutons sociaux orbes glass.
 *
 * Le footer ne flotte pas, donc pas de backdrop-blur sur la surface principale :
 * la matière est composée comme du verre teinté rose. Les composants internes
 * (newsletter, social) utilisent eux backdrop-blur pour donner la sensation de
 * profondeur.
