First off I want to say that this project looks fantastic. I've been maintaining a wordpress site for a while now but am hoping to replace as it was inherited from someone else and so far I'm not a massive fan of the site and/or wordpress so when I get a chance I want to re-architect it.
I have setup a dev box running Automad. I've created some pages and blog posts and all looks ok so far. I have created a couple of galleries without issue but I'm stumped when trying to use the lightbox plugin.
I've added the following to the head variable (tried on the general site settings and on the page itself, but not both at the sametime)
<script src="https://code.jquery.com/jquery-3.4.1.min.js"></script>
<script src="/packages/automad/lightbox/dist/lightbox.min.js"></script>
<link rel="stylesheet" href="/packages/automad/lightbox/dist/lightbox.min.css">
I've then added some text and the image I wish to use in a lightbox when someone clicks on it but I only get the image showing on the page and no pop-up modal etc.

is the markdown in the content section
I guess the section on the lightbox readme about the template variable is important but I have no idea what to do with that
