TensorRT plans its memory for the profile's largest shape, and up to a
whole 6D frame with Best's border (4608 x 6656) it asked for 4.9-5.9 GB
and would not build on the RTX 3050. The profile now ends at 4608 x 3328
(15 MP), tuned for 4160 x 3248, and the tiler cuts a 6D frame into two
such tiles: 27 MP of work for 20 MP kept, against 49 MP in 1408 tiles.
The engine's directory names the profile, so a later range never loads
an engine built for this one.
