## Acknowledgements and Changes

**2022-11-01** Thanks to @Wando for finding a bug in the recognition of slanted rectangles, that lead to a more coherent expansion of the genre rules.
**2023-10-30** Thanks to @SpectriaLimina for noticing an implementation bug, now fixed, which spurred an update to the genre's highlighting and rule panels, plus a new puzzle.
