/* =========================================================================
   Ajuda VM4LEADS — folha de estilo do site de ajuda.

   Segue o VM4LEADS Design System v1 (VM4LEADS-DESIGN-SYSTEM-v1.md):
   noite profundo + branco real + neutros frios + roxo VM4LEADS + acentos
   turquesa/azul/violeta com economia. NADA de bege/creme/paper.

   - Barra lateral: noite #120b2e nos dois temas — diz "isto é VM4LEADS".
   - Barra superior: chapada no violeta da Gestão Executiva — diz "qual app".
   - Fraunces só em título; todo o resto é Inter.
   - Tema escuro com MAIS distância entre superfícies que o claro (§4/§9.3).
