 * ANALYSE DES RÉFÉRENCES DESIGN
 * --------------------------------
 * Sources traitées    : Aucune référence design fournie dans le brief.
 * Palette             : Définie à partir des directives brief — verts profonds, blanc calcaire,
 *                       bois naturel, touche de bleu lac (Léman).
 * Typographie         : Cormorant Garamond (titres, serif élégant évoquant la nature et l'artisanat)
 *                       + Nunito (corps, sans-serif doux et lisible).
 * Structure / layout  : Hero pleine largeur, sections alternées, grille 3 colonnes services,
 *                       grille galerie masonry-like, formulaire centré.
 * Ambiance générale   : Naturaliste, aéré, lumière de plateau alpin — ni corporate ni rustique.
 * Mode appliqué       : Design original guidé par la palette et le métier.
 * Décisions prises    : Séparateurs de section diagonaux pour rompre la monotonie.
 *                       Couleur bois en accent sur hover. Bleu lac réservé aux liens et détails.
 *                       Menu sticky avec fond semi-transparent au scroll.
