Thank you! LGTM - just a few minor issues, as noted inline.

@joewiz Thanks for the speedy review, I just pushed an additional commit to address your suggestions :-)

We have a CI error, which I don't think is related to this PR:

Failed to execute goal com.github.eirslett:frontend-maven-plugin:1.12.0:gulp (gulp build) on project exist-documentation: Failed to run task: 'gulp.js ' failed. org.apache.commons.exec.ExecuteException: Process exited with an error: 1 (Exit value: 1) -> [Help 1]

... but the master branch is passing CI, so why would this PR suddenly throw an error?

[joewiz]

I see there's a dependabot PR for a newer version of eirslett:frontend-maven-plugin, so I'll work through the dependabot backlog and merge that PR. Hopefully that'll fix this.

@dependabot rebase

@dependabot why no love?

ok, since master is green after applying the other dependabot PRs, I'll just merge and hope that master remains green.
