3Co-residency of resident CUDA kernels: every program's nodes must be on the GPU at once, forever, so a load is refused unless all of them fit (per kernel, the block budget, the occupancy shares, and whole-SM nodes against the spread of small blocks); and how many nodes of a shape still fit (`nodes = "fit"`).
