An idea I had for a thermo variant. It should be a GAS - maybe a few steps that require diligent pencil-marking, but the deductions are straightforward.
Solution code: Row 7 (from left to right) then column 7 (from top to bottom)

Very clever solving path would not have expected this constraint to "just work" but it does
