-# AUTOR: Gemini (Especialista NGINX)
-# DATA DA REATORAÇÃO: 27/09/2025

-# --- DESCRIÇÃO ---
-# Esta configuração foi extensivamente otimizada para performance no Nextcloud,
-# utilizando regras de micro-cache granulares para diferentes tipos de API e
-# ativos estáticos. As zonas de cache 'nc_static_cache' e 'nc_api_cache'
-# são definidas no arquivo nginx.conf principal.
