/* ============================================================================
   IMAGINATECH - COMPONENTES DA IDENTIDADE 2026-08
   /shared/components.css  —  segundo <link>, logo apos identity.css.

   Cobre o vocabulario comum dos paineis e paginas: cards, cabecalhos de
   secao, formularios, botoes, badges, tabelas, modais, toasts, tabs,
   empty-state, switches. Tudo em cima dos tokens de identity.css — trocar
   --acc no :root da pagina re-pinta este arquivo inteiro.

   ORDEM DE IMPORT (obrigatoria):
     identity.css -> components.css -> demais shared -> CSS local da pagina
   O CSS local vem por ULTIMO e vence em empate (e onde mora o especifico).

   Classes legadas mantidas de proposito (.btn-primary, .form-input, .modal,
   .stat-card, .toast...) para os HTML existentes nao precisarem renomear nada.
   CUIDADO: nunca escrever asterisco+barra dentro de comentario CSS.
