Pardon the ignorant question, but we're talking about https://tools.wmflabs.org/styleguide/desktop/index.html?

No, that's the old and busted guide. We're talking about the new and sexy one that currently, as far as I know, only exists on Werdna's laptop?

It's on http://living-style-guide.wmflabs.org/ actually. :-)

Ah, I thought there might be decoy copies. Thanks. :-)

I looked at https://phabricator.wikimedia.org/tag/living-style-guide/ and then https://www.mediawiki.org/wiki/Design/Living_style_guide to end up there. I don't know enough about this project to know if http://living-style-guide.wmflabs.org/ is now considered canonical, but when we figure out the best URL, it'd be nice to update Phabricator and mediawiki.org so that everyone can be sure they're discussing the same thing.

This is being done with a combination of code changes (now the demo and the code samples are put together, with the code samples initially collapsed) and templates on the LSG wiki itself.
