Thanks to Kite, who I've rarely encountered.
Started out thinking the puzzle was easy and kind of annoying, but gradually encountered numerous good clues, and it wound up enjoyable and on the challenging side. Some UK spelling and GK required.
FOI 1a. LOI 26, though much of the SE quadrant (especially 13) slowed progress.
Co-COD 28 and 9 by a hair over 20, 1d, 15, 16, 7, 27, 23 and 24.
