Research direction
Start by reproducing the image-generation failure on the listed Debian 12 and Ubuntu 22 systems, comparing the reported driver and CUDA versions. Trace where `is_u32_f32` is loaded and determine what compatibility condition is required; done when the executable runs successfully on the failing environment or the incompatibility is clearly documented.
