- sidebar.php inyecta --brand/--brand-dark desde DB si no fueron definidos ya
  por Layout.php, solucionando que lab_*.php mostraran el sidebar azul (fallback)
  mientras las páginas ERP mostraban verde (#a0a59c del doc_color)
- Gradiente del sidebar invertido: ahora va de más oscuro (top) a brand (bottom)
  en lugar de terminar con mezcla blanca que perdía las letras
