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.

MODULAR LINE:
• Every set of three adjacent values on the teal line must contain one of each residue class modulo 3;
• I.e. one value from [1, 4, 7, 10...], one from [2, 5, 8, 11...] and one from [3, 6, 9, 12...].

Solution code: Row 6 (bottom), left to right

Working my way through the series, I think I have finally sorted out the fundamentals which make these much more approachable.

So good of a puzzle that I didn't even notice the socials button

Wild that has a unique findable solution with one relatively small mod line. Fortress fillomino go brr

One of my favourite of this series that I've done, some very cool logic in this one.

30 minutes staring at this line and no progress whatsoever

Solved it in 50, using very shaky logic I'm not confident about at all. Definitely 2* or above
