# Nginx del contenedor frontend (HTTP interno, puerto 80 → publicado en 8075).
#
# Flujo HTTPS (igual que orcid2sword en Sinbad2):
#   1. Usuario → https://sinbad2.ujaen.es/generadorexamenesllm/
#   2. Apache termina TLS y hace ProxyPass al puerto 8075 (HTTP).
#   3. Con ProxyPass ... http://host:8075/  Apache QUITA el prefijo /generadorexamenesllm
#      y el contenedor recibe /, /assets/, /auth/, etc.
#   4. Acceso directo al puerto 8075 (sin Apache) usa el prefijo /generadorexamenesllm/
#      porque el build de Vite lleva VITE_APP_BASE_PATH=/generadorexamenesllm/
