Non-Consecutive Fillomino

Divide the grid into connected blocks whose size matches the number in every cell. Touching blocks must differ by at least two.
Controls
Fill every cell with a number. Connected cells with the same number form a block, and the number equals the block’s cell count. Blocks of the same size cannot share an edge. Two touching blocks may not have consecutive sizes, so their sizes must differ by at least two.
