Christmas Pentominous
Merry Christmas to all. Here's a smooth pencil puzzle to relax with this Christmas.
Divide the grid so that every cell belongs to exactly one pentomino (orthogonally connected five-cell regions). No two pentominoes of the same shape may share an edge (including rotations and reflections). Letters in the grid represent which pentomino shape that cell belongs to (see pentomino key below).
Solution code: Number of P Pentominoes in the grid followed by the number T Pentominoes

Nice puzzle!
The Penpa link doesn't work for me directly; it takes me to an error page that says it "was created using a deprecated API end point", whatever that means. Instead, I used https://marktekfan.github.io/sudokupad-penpa-import/ to convert it to a SudokuPad link, which is too long to include here.
