In each grid, normal 4x4 Sudoku rules apply.
X-SUMS - On each grey tab, write some number that acts as an "x-sums" clue in both directions, i.e. moving into a grid from the tab, the first N cells sum to its number, where N is the first digit seen. (Different tabs may have different X-sums.)
FOLDED ANTISYMMETRY - If the puzzle were folded along one dashed line, and then along the other, no digit would overlap another identical digit.
Solution code: Bottom row (9 digits)

I really enjoyed this take on disjoint grids. Lovely when a puzzle encourages you to imagine crumpling it up a little before you even begin!
