FORTRESS FILLOMINO:
• Divide the grid into orthogonally connected regions and fill each cell with a number (not necessarily single-digit) showing the number of cells in the region to which it belongs;
• Each region must be either strictly larger than all of its orthogonal neighbours or strictly smaller than all of its orthogonal neighbours.
ZIPPERS:
• For each lavender Zipper line, pairs of values equidistant from the centre sum to the same total, N, which for odd-length lines is the value in the central cell.
Solution code: Column 10 (rightmost), top to bottom

Really nice to see a puzzle in the series with some trickier, more intricate logic!
