      # IMPORTANT: Change SECRET_KEY in production! Used for sessions and CSRF tokens.
      # Generate a secure key: python -c "import secrets; print(secrets.token_hex(32))"
      # 
      # CSRF CONFIGURATION:
      # - WTF_CSRF_SSL_STRICT: Set to 'false' for HTTP access (localhost or IP address)
      #   Set to 'true' only when using HTTPS in production
      # - If accessing via IP address (e.g., 192.168.1.100), also set:
      #   SESSION_COOKIE_SECURE=false and CSRF_COOKIE_SECURE=false
      # 
      # TROUBLESHOOTING: If forms fail with "CSRF token missing or invalid":
      # 1. Verify SECRET_KEY is set and doesn't change between restarts
      # 2. Check CSRF is enabled: WTF_CSRF_ENABLED=true
      # 3. Ensure cookies are enabled in your browser
      # 4. If behind a reverse proxy, ensure it forwards cookies correctly
      # 5. Check the token hasn't expired (increase WTF_CSRF_TIME_LIMIT if needed)
      # 6. If accessing via IP (not localhost): WTF_CSRF_SSL_STRICT=false
      # For details: docs/CSRF_CONFIGURATION.md and docs/CSRF_IP_ACCESS_GUIDE.md
