   grosamael.store : domotique et électronique, fait main.

   Identité volontairement distincte du portfolio grosamael.fr : ici c'est un
   atelier, pas une vitrine commerciale. Papier chaud, accent brique, titres
   en serif. Même grammaire visuelle en revanche : filets fins, libellés en
   mono, aucune carte encadrée.

   Tout passe par les variables : le mode sombre n'a aucune règle dédiée en
   dehors du bloc [data-theme="dark"].
