   UIASS Online — feuille de style principale
   --------------------------------------------------------------------------
   Sommaire :
     1. Variables (design tokens)
     2. Base (typographie, fond)
     3. Boutons
     4. Formulaires (inputs, selects, labels)
     5. Alertes & messages flash
     6. Page de connexion
   --------------------------------------------------------------------------
   Chargée APRÈS bootstrap.min.css (v4.5.2) : ne redéfinit que ce qui est
   nécessaire au design UIASS, le reste s'appuie sur Bootstrap.
