/* ============================================================
   Maldaner — correctifs mobile
   Retours Thomas Thiollay (Maldaner) du 01/09/2026
   Préparé le 03/09/2026 · NON APPLIQUÉ (accès SFTP pagination-web.fr à obtenir)

   À coller à la FIN de css/style.css, après le bloc
   @media (max-width: 900px) existant (ligne ~1959).
   ============================================================ */


/* ------------------------------------------------------------
   1. « Sensation de flottement droite/gauche » sur l'accueil
   ------------------------------------------------------------
   Mesuré au viewport 375 px : scrollWidth = 410 px, soit 35 px de
   débordement horizontal. Coupable : .hero-engine, qui reste en
   position:absolute / width:130% / right:-25% en mobile — la règle
   desktop (style.css ~ligne 487) n'est jamais neutralisée sous 900 px,
   alors que .hero-shape l'est bien (ligne ~2028).

   Le débordement rend la page scrollable latéralement : au moindre
   geste de zoom/dézoom, elle « flotte » de droite à gauche.
   Deux verrous : on recadre l'image, et on coupe le débordement à la racine. */

@media (max-width: 900px) {
  .hero-engine {
    position: relative;
    width: 100%;
    max-width: 420px;
    right: auto;
    top: auto;
    transform: none;
    margin: 0 auto;
  }

  /* .hero est en overflow:visible (ligne ~437) : on le referme en mobile. */
  .hero { overflow: hidden; }
}

/* Filet de sécurité global : aucun élément ne peut plus créer de
   défilement horizontal, quelle que soit la page. */
html, body { overflow-x: hidden; }


/* ------------------------------------------------------------
   3. Barre blanche sous « L'imprégnation » et « Services »
   ------------------------------------------------------------
   Mesuré : les deux .dropdown fermés font 16 px de haut, fond blanc.

   Cause : le reset global applique box-sizing:border-box (ligne 46).
   Avec border-box, max-height:0 NE compresse PAS le padding — la
   hauteur plancher reste padding-top + padding-bottom, soit
   2 × var(--space-sm) = 2 × 8 px = 16 px. Comme .dropdown a
   background:white en mobile (ligne ~2000), ces 16 px se voient.

   Correctif : padding vertical nul à l'état fermé, restauré à
   l'ouverture.

   ⚠️ NE PAS ajouter « padding » à la transition. La .nav fermée est en
   visibility:hidden : une transition sur le padding ne s'y exécute jamais
   et la valeur calculée reste bloquée à sa valeur de départ (8 px) — la
   barre blanche réapparaît. Vérifié en conditions réelles le 03/09/2026.
   La transition ne porte donc que sur max-height ; le padding bascule
   sèchement, ce qui ne se voit pas puisque le bloc est clippé. */

@media (max-width: 900px) {
  .dropdown {
    padding-top: 0;
    padding-bottom: 0;
    transition: max-height 0.3s ease;
  }

  .has-dropdown.is-open .dropdown {
    padding-top: var(--space-sm);
    padding-bottom: var(--space-sm);

   2. Photo qui empiète sur le texte dans Services — NON REPRODUIT
   ------------------------------------------------------------
   Testé à 375, 600, 797 et 935 px : aucun chevauchement entre
   .service-content et .service-media. Le correctif ci-dessous ne
   traite donc PAS le symptôme décrit, mais un défaut réel constaté
   au passage, qui en est un candidat plausible.

   Constat : services-sous-traitance.png est en loading="lazy" et,
   tant qu'elle n'est pas chargée, .service-media mesure ~2 px de large
   (naturalWidth 0, complete false). L'espace n'est donc pas réservé :
   au chargement, le bloc passe de 2 px à pleine largeur et pousse le
   texte d'un coup. Sur un téléphone en 4G, mi-défilement, ce saut
   ressemble exactement à « la photo empiète sur le texte ».

   aspect-ratio seul ne suffit pas ici parce que la largeur de départ
   est nulle : on impose donc une largeur pleine dès avant le chargement. */

.service-media {
  width: 100%;
}

.service-media img {
  width: 100%;
  height: auto;
  aspect-ratio: 4 / 3;

/* À confirmer avec Thomas : capture d'écran + modèle de téléphone et
   navigateur. Sans ça, on corrige à l'aveugle. */
