^ This is indeed the right answer - applying the layout is part of the
template processing - so if you've used template() to generate content
from a template, the layout is applied, but if you've just returned
content, it's assumed that that's the content you want sent to the
client - in other words, whatever the route handler returns is what
goes to the client, whether that's the result of a template() call, or
just some content you generated.

If you want to apply the layout around some generated content without
having to put it in a template file, you can use the template engine's
apply_layout() method to do it, e.g.:

get '/' => sub {
    # get the template engine
    my $template_engine = engine 'template';

    # apply the layout (not the renderer), and return the result
    return $template_engine->apply_layout("Home Page");
};
