Cause of death: the autopsy

The limits come from safety standards (UL 60335-2-40 and ASHRAE 15) about flammability, so a wrong answer is a safety risk. Even with live search demand, it fell from 16 to 8 on liability.

The numbers

None. It was never built, so there are no visitors, sales or ad spend to count. It died on paper, which is the cheapest place to die.

Could rise again if

The report left no way back.
