# Il backend espone la porta 5000 sull'host mappata su 8080 nel container.
# Il frontend punta sempre a localhost:5000.
# Il healthcheck su postgres e' necessario.
# Senza, il backend parte prima che PostgreSQL sia pronto ad accettare connessioni e crasha.
# depends_on con condition: service_healthy risolve la race condition di startup.
