  # 1. "File Load" phase.
  file_proxy = Lowkey[file_path] || Lowkey.load(file_path)
  templates = wrap_render_methods(file_proxy:)

  # 2. "Class Load" phase.
  # Not a security risk because "eval" is equivalent to "load" or "require_relative" in this context.
  eval(file_proxy.export, top_level_binding, file_proxy.file_path, 0) # rubocop:disable Security/Eval

  # 3. "Runtime" phase (before low nodes are rendered).
  # Templates only exist if antlers gem has been required by another gem (such as LowNode) and the template contains antlers syntax.
  templates.each do |namespace, method_template|
    klass = Object.const_get(namespace)
    method, template = method_template
    # TODO: If params contain "**props" or similar then send that, so that LowNode can replicate it.
    params = method.params.map(&:name)

    next unless supports_templates?(klass) || raise(UnsupportedTemplate, "Template for '#{namespace}' identified but not implemented")

    # TODO: Make template engine configurable.
    klass.build_template(template:, params:, engine: Antlers, namespace:)
