There's a full writeup (in the link above to avoid spoilers in case anyone's still working on it). Thanks to everyone who submitted, and everyone who sent kind words in your answer emails—it always means a lot. Out of 50 entries, the randomly selected winner is Malaika "7x7 overlord" Handa! Congrats to Malaika, and everyone who solved!
And, an announcement: I'm excited to be joining the Atlantic puzzles team as assistant crossword editor! What does that mean for the future of this site? Who knows, really. Free time's going to be a big limiting factor, but my goal is to keep posting for a little while, since (a) I have a lot of unclued grids I'm sitting on, and (b) I just wanna get to Puzzle #100.
Big-stacks themeless today. Hope you enjoy!
