   etancheite-broye.com — « bitume & cuivre »
   Registre technique sombre : bitume, membranes, solins cuivre. Aurore à
   plusieurs foyers posée au repos (pas seulement au survol), grain léger,
   profondeur de calque réelle. Le contenu ne dépend jamais du JS ni du
   scroll pour être visible — le JS ajoute seulement une classe d'amorce.
