/* ============================================================
   Yoga Lumière — studio yoga & Pilates, Orvault (44)
   Feuille de style unique. CSS vanilla, mobile-first.

   Charte : les tons crème + sable rappellent le parquet bois et
   les murs chaulés d'un studio yoga européen. La terre cuite
   (#B07A55) évoque la chaleur du tapis et de la lumière du soir.
   Le vert sage (#7C8B7A) introduit une touche végétale sans verser
   dans le "vert wellness". L'anthracite chaud (#2A2724) reste
   lisible sans agressivité.
   Polices : Fraunces (titres, serif souple) + Inter (texte).
