Cryptic crossword No 1,702

Sorry, Nina's locked up today but the combination's written on the lock if you need to get in.

Enjoyed this a lot on CS today, juff. Quite glad I hadn't done it: nice to see the live solve and not know the answers. Plenty of creative constructions in here. Thanks. PM

Thanks juff. Particularly enjoyed 8d, 23d and the matching pair of 15a and 18d. And the thematic punchline is very neat. Some spoilers:

Some real delights here for me. 5D is a great fun, 24A a wicked innovation, and the surfaces for 13A and 30A shiny smooth. I really appreciate the general fresh and punchy approach to clue construction!

A bit slow to get to this Juff, but worth the wait. Some of the more subtle constructions and obscure definitions had me going for a while, but I got there in the end. Particularly enjoyed 11a, 14a, 28a, 30a, 18d, 20d, 23d among others. Spoilers in reply…
