  # serialization functions, and helper functions (MarshalForm) are NOT embedded
  # in the output. Instead, the generated code imports them from three sub-packages:
  #   <path>/types   — custom types (Date, Email, UUID, File, Nullable)
  #   <path>/params  — parameter style/bind functions (StyleSimpleParam, BindFormParam, etc.)
  #   <path>/helpers — utility functions (MarshalForm)
  #

  #   oapi-codegen --generate-runtime <base-import-path>
  #
  # Default: not set (all helpers are embedded in each generated file)
