/* ==========================================================================
   Módulo E-mail — Fase 1 (03/09/2026): SÓ INTERFACE, com mensagens de exemplo
   vindas do model. Desenho pedido pelo Felipe, na linha dos clientes
   tradicionais (a referência que ele mandou foi o Proton Mail):

       [rail de ícones] [lista densa] [leitor]

   O rail mostra APENAS os ícones das pastas — o nome aparece no hover.
   Classes namespaced `ml-*`. Tokens e fontes são os do app.
