* Add some conditional logic so that company names don't get shown for
hobbyists or students
* Add a greyscale filter to text for more accurate preview
* Always default to SVG preview as it's the most accurate (cairo

png/pdf)
* Always use roboto font.

* Add ability for a user to preview their own badge
* Add a template for the LCA2018 badge
