Notes

• All environment variables can also be set via CLI flags using kebab-case (e.g., --postgres-host)
• SERVARR_ADMIN_PASSWORD is only required for Servarr types (sonarr, radarr, prowlarr, etc.), not for bazarr or qbittorrent
• SERVARR_TYPE=auto attempts to detect the service type from the URL
• When SERVARR_TYPE=bazarr, PrepArr manages Bazarr’s config.yaml (not config.xml) and uses BAZARR_URL/BAZARR_API_KEY for API access
