Who cut up my sudoku?

Assemble the 16 tiles into a complete 4×4 sudoku grid, subject to:

1. Sudoku: Digits 1–4 appear once in every row, column, and 2×2 box.
2. Edges: Frame and box borders are thick; edges inside a box are thin.
3. Curves: Blue curves on neighbouring tiles must join across shared edges. In the finished grid, every curve forms a closed loop.

Tiles may not be rotated or flipped. The puzzle has a unique solution.
