Puzzles #505 & #506 - 24 Hour Doppelblocks

I also provided a Doppelblock puzzle (worth 60 points) and "filler" puzzle that went unused for the 2020 2023 24 Hour Puzzle Championship. I ended up resorting to some given digits in the main puzzle since I ran out of possible clues (lazy past me) but since it could stay on-theme and let me remove another clue, I liked it enough.

Penpa used for the second image so the givens aren't green.
