Review Comment:
The `{{{{data}}}}` syntax in the documentation is actually correct
Handlebars — it's the triple-stache `{{{data}}}` (unescaped output) rendered
inside a fenced code block where the outer braces are part of the
Jinja2/template escaping. However, I'll clarify the documentation to avoid
confusion. Thanks for flagging\!
