Killer Look-and-Say Islands

- Normal Sudoku Rules Apply
- Normal Killer cage rules Apply
- Normal Look and Say rules Apply
- Ambiguity rules apply - Cages are either Killer only, Look-and-Say only, or both killer and Look-and-Say. Which cage is which is to be determined by the solver.
Normal Sudoku rules apply. Place the digits 1-9 in each row, column, and box.
Every marked cage is either a Killer cage, a Look-and-Say cage, or both Killer and Look-and-Say.
Within Killer cages, digits must not repeat, and must sum to the total given in the top left corner.
Within Look-and-Say cages, the ones digit of the number in the top left corner indicates a digit that appears in that cage, and the tens digit indicates how many times the ones digit appears in that cage. For clarity, digits may repeat in Look-and-Say cages even if they are also killer cages.
Each cage is a part of an "island" formed of three cages all of size N, where it is possible to reach all three cages by traveling only orthogonally through cages of size N. Within these islands, one cage is a Killer cage, one cage is a Look-and-Say cage, and one cage is both.
Thanks to djorr here on LMD for the initial inspiration!
Solution code: Row 8 from left to right followed by column 9 from top to bottom (18 digits, no spaces)
