Ugh. Replaced one typo in the above toot, and a new one arrived - but too late now. Letting it go.
There are some very good official reports linked in the piece, if anyone's inclined to do a deep dive. As always, my aim was to write in a way that makes the issue accessible. There's a lot more that could have been said, but hopefully this gets most important broad strokes across.

I'm fluent in Typo. As long as the link works...it be A OK
