Rent per SF is the genome of the floor plan.

Drag the rent/SF slider. Watch the floor plan reorganize — units shrink or expand, the mix shifts, corridors compress. The genome doesn't change the building's DNA. It IS the DNA.

Low rent/SF = bigger units (fewer, fatter, to hit rent targets). High rent/SF = smaller units (more, thinner, because every SF pays). The rent genome writes the plan.
