So this would add the meta tags as translatable strings. I'm pretty sure that's not what you want. I think what we need is the `{% with %}` tag instad of the blocktrans. That would allow you to set the variable and then use it inside. That or just do the old-fashioned thing and put the string in there twice :)

Also, since these are both meta tags and have the same content attribute, can they be combined into one tag with a name, property, and content? Or is that not how SEO and OG stuff likes to work?
