### Alphabet Soup

Written on November 4, 2022. Warning: This puzzle is extremely hard.

This puzzle has some special rules: each thermo displayed in the right grid must be placed in a unique $3 \times 3$ subgrid on the left grid. Moreover, the position of each thermo must not change with respect to its subgrid (meaning no rotation or translation within the subgrid).

The line is a German Whisper. As far as I know, F-Puzzles does not have an option to create a German Whisper, so it does not have any error checking. (Penpa does not either, and placing XV’s is annoying, so I opted to use F-Puzzles instead.)
