I hope everyone is having a lovely Supersized Saturday! And what could possibly be more supersized than two puzzles in a single grid. Today's puzzle is a type of hybrid puzzle known as a Permaculture, specifically a mashup of Masyu and Isowatari. While the difficulty of the puzzle should be appropriate for GAPP, I strongly recommend that you've solved at least one standard Masyu and one standard Isowatari before. You can find plenty of both in the GAPP archives, but here is a direct link to one of each:

Masyu by Freddie: Archive: Wednesday, 4 October 2023
Isowatari by Walker: Archive: Friday, 10 November 2023

Rules:
Permaculture: Divide the grid into two regions along dashed lines. Solve one region as a Masyu and the other as an Isowatari.
Masyu: Draw a non-intersecting loop through the centers of some cells that passes through every circle. The loop must turn on black circles and travel straight through the cells on either side. The loop must go straight through white circles, and turn in at least one of the cells on either side.
Isowatari: Shade some cells so that all unshaded cells form one orthogonally connected area and no 2x2 region is entirely unshaded. Black circles must be shaded and white circles must be unshaded. All orthogonally connected groups of shaded cells must be the size indicated above the grid.

Answer check looks for the loop in Masyu (Line or Composite mode), the shaded cells in Isowatari (Surface mode), and the boundary between them (Edge mode)
