    # Not using Lono::Template::Context because that works differently.
    # That is used to load a context object that is passed to RenderMePretty's context.
    # So that we can load context for params files and erb templates.
    #
    # In this case builder is actually the dsl context.
    # We want to load variables and helpers into this builder context directly.
    # This loads additional context. It looks very similar to Lono::Template::Context
