/* Feuille de style autonome des pages /guides/ (SEO, hors funnel).
   Volontairement indépendante du bundle Tailwind de l'app (qui purge les
   classes non utilisées côté React) : ces pages sont du HTML statique généré
   au build par scripts/build-guides.mjs, donc une CSS dédiée, légère et
   stable, garantit un rendu identique quel que soit le contenu ajouté plus
   tard. Palette alignée sur l'app (slate-950 / indigo / violet). */
