As promised in Best pratices? - #6 by cshoredaniel, I have revived
and have also brought the Hugo debug tables demo site back from the bitbucket.
Thank you to @iaeiou for expressing interest in the module, and I hope it proves useful to others as well.
EDIT: I have updated the CSS on the debug tables demo site (above) and the demo site for a minimal test theme for Hugo by DFD (which is the theme used by the debug tables demo site) so that they are sufficiently mobile-friendly to get all 100’s on web.dev’s Lighthouse based tests.
I hope this proves useful to others as well as myself.
