/* ═══════════════════════════════════════════════════════════════════════════
   HEXTECH IA — PAINÉIS (panels.css)
   ═══════════════════════════════════════════════════════════════════════════

   CAMADA 3 dos painéis (login, painel do cliente, painel admin).
   Depende de hextech-tokens.css + hextech-ui.css. Prefixo `.pn-`.

   ESTRUTURA DO SHELL (mesma nos dois painéis):
   .pn-shell                → grid [sidebar | main]
   ├── .pn-sidebar          → logo, navegação por seções, sair
   └── .pn-main
       ├── .pn-topbar       → título da seção + chip do usuário
       └── .pn-content      → seções (.pn-section, só a ativa é visível)

   COMPONENTES: .pn-kpi (cartão de métrica), .pn-table (tabela de dados),
   .pn-field/.pn-input (formulários), .pn-toast (feedback), .pn-drawer
   (detalhe de registro), .pn-banner (avisos de sistema).
