Usage: ./scripts/setup-appstore-mimic.sh [options]

Prepares a Docker env to mimic app-store installation behavior:
- isolates Nextcloud custom_apps mount from source tree
- seeds packaged-style app copies into that isolated path
- keeps user_oidc available for OIDC bootstrapping

Options:
  --env-file <path>            Env file to modify (default: .env.devprod)
  --custom-apps-path <path>    Host path for NEXTCLOUD_CUSTOM_APPS_PATH
                               (default: ./nextcloud/custom_apps_appstore)
  --no-refresh-qortal          Do not overwrite existing qortal_integration copy
  -h, --help                   Show this help
