Thank you HamishSoup, I thought it might be the font.
There must be a rule that stops setters explaining specific clues because, over all of the years, I haven't seen it done... ever! And, of course, the published solutions never go into such detail (although yours will have to, which will be nice).
The only other tiny 'grudge' I bear you has to do with that capital letter in 9ac - but never mind, thank you for a very enjoyable puzzle!
