This aligns frontend build defaults and CI deploy variables with the real proxy mount so the app is served under /deckofcars/generadorexamenesllm instead of falling back to the Sinbad homepage.
Replace the inline SSH command with a YAML-safe block scalar and heredoc so the pipeline parser accepts the script while keeping the same port-conflict handling logic.
Parametrize compose published ports and add CI safeguards to detect and release occupied frontend/backend ports before docker compose up, preventing bind errors on 8075.
Configure GitLab deploy pipeline for this app and switch backend/frontend endpoint defaults from localhost to sinbad2.ujaen.es, including Docker, env files, API client, CORS, and docs.
