/* ============================================================
   SCIP — site vitrine · base partagée.
   Identité = celle du logiciel (charte v1.0, source unique :
   apps/web/src/app/globals.css). Mêmes tokens, mêmes polices
   (IBM Plex Sans / Sans Condensed / Mono), mêmes composants :
   .btn en pilule, .segmented, .panel plat, .chip, .t-label.
   Palette volontairement pauvre : 90 % de gris neutre, l'encre
   porte la seule action, la couleur n'apparaît que sur les
   événements, le violet ne dit que « démo » ou « simulé ».
   Ce que le site ajoute au logiciel : l'échelle (titres et mots
   géants en Plex Sans Condensed 700), la profondeur des fenêtres
   de capture (perspective + ombres de la charte), le flou de la
   barre de navigation.
