Prism is a new variant invented by Leeor (I Love Sleeping). It is currently local to Akari 美術館 but may later be expanded to Akari (RGB) and possibly other genres. The implementation is also a stepping stone for the upcoming mirror variant.

Acknowledgements and Changes
2024-04-15 Many thanks to Anurag Sahay for sending a puzzle to mark the rollout, and for feedback on the implementation.

!
2024-04-21 Joelangstaff shared the first three (classic) puzzles of an ongoing set created by a process that starts with a dice roll
2024-04-26 A small regression on the hex
grid detected by PinkHoodie was corrected (cause: changes in the number templates to support an upcoming input mode)
2024-04-26 puzzletters PinkHoodie sent 2 puzzles using variants hex,clues-missing,shade-no-adjacent
and shade-zones-1,unshade-zones-1,shade-no-vertex,unshade-no-vertex,shade
!
2024-04-28 Sketch lines enabled, since they might be useful large puzzles under certain conditions, a suggestion by Joelangstaff, who rolled the dice again. Also, a visual regression where aux marks were no longer fading was corrected (cause: prior solution was non-systematic)
2024-05-03 A recent regression affecting the shade
variant in Akari 美術館 was corrected (cause conflict with given shaded tiles). Thanks Random 8.

2024-06-05 The local prism
variant by Leeor (I Love Sleeping) was added, alongside an example puzzle! Thanks Leeor (I Love Sleeping) for finding a missing constraint in the highlighting (no bulb on prism). Thanks to PinkHoodie for detecting diagonal self-lighting wasn't always being detected and that the prism was available on solve mode.
2024-06-06 Highlighting incorrections (with zero lights and a prism) discovered by PinkHoodie were corrected (cause: highlighter was skipping an aggregation step rather than reporting it as empty)
