NB: `<textarea id="mt">` and `<div id="mtr">` in the regular markdown editor must have the same font; none of the suggestions above will cause any issues but keep it in mind if you're getting creative
# `<head>`
to add stuff to the html `<head>`, for example a css `<link>` or `<meta>` tags, use either the global-option `--html-head` or the volflag `html_head`
if you give it the value `@ASDF` it will try to open a file named ASDF and send the text within
if the value starts with `%` it will assume a jinja2 template and expand it; the template has access to the `HttpCli` object through a property named `this` as well as everything in `j2a` and the stuff added by `self.j2s`; see [browser.html](https://github.com/9001/copyparty/blob/hovudstraum/copyparty/web/browser.html) for inspiration or look under the hood in [httpcli.py](https://github.com/9001/copyparty/blob/hovudstraum/copyparty/httpcli.py)
