Coverage report

This PR does not seem to contain any modification to coverable code.

Side note / thought: I think we could benefit from extracting out some of the common pieces that we've been copy-pasting around (like the usertools block, Bootstrap import, etc.) as include templates. This can be a separate issue / PR.
