/* ==========================================================================
   SGE - Sistema de Gestao Escolar
   Design system proprio construido sobre o Bootstrap 5.

   Referencias visuais: Google Workspace, Microsoft 365 e ERPs modernos.
   Principios adotados:
     - Superficie clara, hierarquia por elevacao sutil (nunca por bordas duras)
     - Densidade de informacao alta, porem respiravel
     - Toque confortavel em tablet e celular (alvos >= 44px)
     - Nenhuma dependencia externa: tudo servido localmente (exigencia da CSP)
