def rails_pulse_csp_nonce
  # Try various methods to get the CSP nonce from the host application
  nonce = nil

  # Method 1: Check for Rails 6+ CSP nonce helper
  if respond_to?(:content_security_policy_nonce)
    nonce = content_security_policy_nonce
  end

  # Method 2: Check for custom csp_nonce helper (common in many apps)
  if nonce.blank? && respond_to?(:csp_nonce)
    nonce = csp_nonce
  end

  # Method 3: Try to extract from request environment (where CSP gems often store it)
  if nonce.blank? && defined?(request) && request
    nonce = request.env["action_dispatch.content_security_policy_nonce"] ||
            request.env["secure_headers.content_security_policy_nonce"] ||
            request.env["csp_nonce"]
  end

  # Method 4: Check content_for CSP nonce (some apps set it this way)
  if nonce.blank? && respond_to?(:content_for) && content_for?(:csp_nonce)
    nonce = content_for(:csp_nonce)
  end

  # Method 5: Extract from meta tag if present (less efficient but works)
  if nonce.blank? && defined?(content_security_policy_nonce_tag)
    begin
      tag_content = content_security_policy_nonce_tag
      if tag_content && tag_content.include?("nonce-")

      end
    rescue
      # Ignore parsing errors
    end
  end

  # Return the nonce or nil (Rails will handle CSP properly with nil)
