/* ============================================================================
   theme.css — Design system du briefing décollage CEPS09
   "EFB day-mode, chrome cockpit" — contenu CLAIR lisible au soleil, encadré
   par des bandes de chrome sombres (en-tête, stepper, nav basse) comme un
   EFB en mode jour. Sobre et plat : hiérarchie par filets 1 px, pas d'ombres.
   Discipline couleur = signification : cyan = interactif / sélection ·
   vert = conforme · ambre = caution uniquement · rouge = stop.
   Les infos décisionnelles sont MISES EN ÉVIDENCE : verdicts en bandeaux
   pleins (GO/NO-GO), readouts clés en gros mono avec liseré de statut.

   Type : IBM Plex superfamily — Sans (texte), Sans Condensed (étiquettes
   d'instrument, capitales espacées), Mono (chaque valeur, chiffres tabulaires).

   Le chrome sombre utilise des littéraux (--chrome-*) ; le contenu utilise
   les tokens clairs ci-dessous.
