/* ============================================================================
   PORTAIL CLIENT NTEC — feuille de style v2 « Acier » (refonte 2026-07-25, demande N)
   ----------------------------------------------------------------------------
   - Identité visuelle DANS LA LIGNÉE du bureau NTEC Gestion : bleu Acier à plat
     (#1c5aa0 / #2e6db8), fond #ecf1f7, AUCUN dégradé (règle N du 25.07),
     élévations douces, coins arrondis, sémantique de couleurs stable
     (bleu = action · vert = ok/payé · orange = attention · rouge = retard/refus).
   - DEUX THÈMES : clair (défaut) + sombre — piloté par [data-theme] (portal.js,
     mémorisé localStorage) avec repli automatique prefers-color-scheme.
   - TOUS les sélecteurs historiques sont conservés (zéro perte de fonction) ;
     ajouts : .button.danger, .icon-button/#theme-toggle, .modal-actions déjà là.
   - CSP style-src 'self' : tout le style vit ici, jamais d'inline.
