/* ============================================================
   OPTERIA : page « Sécurité des données » (06/10/2026, demande Axel) : la seule page du site en mode sombre.
   Esprit gleap.ai/kai en thème sombre : gris superposés (#141414 page, #1f1f1f cartes, #2a2a2a cadres), titres blancs
   avec une seconde phrase grise, la couleur vient des peintures OpterIA et de quelques lueurs, maquettes blanches posées dessus.
   Tout est rangé sous body.page-sombre : aucune autre page n'est touchée. Chargée après da-gleap.css et da-cerveau.css.
   Animations : securite.js (transform, opacity, stroke-dashoffset seulement).
