Shaded Skyline

 I just made this while thinking about interpreting a three-dimensional puzzle with two-dimensional cross-section rulesets. I'm pleasantly surprised it worked out to only need one clue.

Solve the Skyscrapers puzzle in such a way that each digit counts the amount of squares that should be shaded in that digit's position in the five incomplete shading puzzles below. A square may only be shaded if it is also shaded in the puzzle immediately to its left, with the exception of the leftmost puzzle, which is entirely shaded. Each layer uses a different puzzle type from the layer candidates. No clues or given edges have been revealed for the shading puzzles. All rulesets can be found at https://pzprxs.vercel.app/list.html
