def self.help_text
  <<~HELP
    Deploy your Belt application to AWS.

    Usage: belt deploy [environment] [options]
           belt deploy frontend <environment>

    This runs the full deployment lifecycle:
      1. Ensure Gemfile.lock is consistent (fix stale PATH refs)
      2. terraform init    (initialize providers/modules)
      3. terraform plan    (preview changes)
      4. Prompt for confirmation (unless --auto)
      5. terraform apply   (deploy changes)

    Options:
      --auto, --yes, -y    Skip confirmation prompt (auto-approve)
      --rebuild            Rebuild and push Lambda code directly (bypasses Terraform).
                           Much faster for code-only changes ā€” packages gems via Docker,
                           zips, and pushes with `aws lambda update-function-code`.
      -h, --help           Show this help

    Environment:
      Defaults to BELT_ENV if set, otherwise the first available environment.

    Examples:
      belt deploy                # Deploy dev (or BELT_ENV)
      belt deploy prod           # Deploy to prod
      belt deploy dev --auto     # Deploy without confirmation (CI mode)
      belt deploy --rebuild      # Fast code push to dev (no infra changes)
      belt deploy prod --rebuild # Fast code push to prod
      belt deploy frontend dev   # Deploy frontend assets only
