* Filters the template enhancement output buffer prior to sending to the client.

* This filter only applies the HTML output of an included template. This filter is a progressive enhancement
* intended for applications such as optimizing markup to improve frontend page load performance. Sites must not
* depend on this filter applying since they may opt to stream the responses instead. Callbacks for this filter
* are highly discouraged from using regular expressions to do any kind of replacement on the output. Use the
* HTML API (either `WP_HTML_Tag_Processor` or `WP_HTML_Processor`), or else use {@see DOM\HtmlDocument} as of
* PHP 8.4 which fully supports HTML5.
*
* Do not print any output during this filter. While filters normally don't print anything, this is especially
* important since this applies during an output buffer callback. Prior to PHP 8.5, the output will be silently
* omitted, whereas afterward a deprecation notice will be emitted.
*
* Important: Because this filter is applied inside an output buffer callback (i.e. display handler), any
* callbacks added to the filter must not attempt to start their own output buffers. Otherwise, PHP will raise a
* fatal error: "Cannot use output buffering in output buffering display handlers."
*
* @since 6.9.0

* @param string $filtered_output HTML template enhancement output buffer.
