Tapa 4 in 1 (460)

Shade some cells to create a continuous wall. Numbers in a cell indicate the length of consecutive shaded blocks in the neighboring cells. If there is more than one number in a cell, there must be at least one white cell between the shaded blocks. Shaded cells cannot form a 2x2 square. Cells containing numbers cannot be shaded. The middle grid contains clues to four different tapa puzzles. Split the clues into four sets of clues. Each clue must belong to exactly one grid. Clues of different grids do not overlap.
