Edge logic required to get anywhere on this puzzle. It might fall into deep lookahead, but maybe not. I focused on edge logic on the top row. Sometimes the conflict for the edge logic is in row 4 or 5, but eventually, working steadily, I was able to place the entire top two rows. The rest of the puzzle fell into place after that.

Here's what I did

distant edge logic on the 9 in r20 rules out c1-16 and c33-35
LL

DEL on the 9 in r1 rules out c1-11
LL to finish

Found to have a unique solution by infrapinklizzard.

Found to be solvable with moderate lookahead by infrapinklizzard.
