/* ══════════════════════════════════════════════════════════════════
   NIAKS TECH — NIAKS ASSISTANT (bouton + fenêtre de chat)
   ------------------------------------------------------------------
   Empilé au-dessus de #wa-float, même coin — #wa-float garde sa
   propre règle CSS dans shell.css intégralement inchangée. Tout ici
   est position:fixed : impact CLS nul, aucun élément ne pousse le
   contenu de la page.

   Pendant que le panneau est ouvert (body.na-open), le bouton NIAKS
   ET #wa-float s'effacent : sur mobile surtout, les garder visibles
   en permanence aurait mangé une bonne partie de la hauteur utile du
   panneau pour rien — personne ne clique sur WhatsApp en pleine
   conversation avec NIAKS. #wa-float est réduit via `transform`, la
   SEULE propriété que sa transition dans shell.css anime déjà : on
   ne redéclare jamais sa règle `transition` ici, pour ne jamais
   pouvoir la faire diverger d'un futur changement dans shell.css.
