PyTorch's `torch.cuda.get_device_properties(0)` returns a
`_CudaDeviceProperties` object whose memory attribute is
`total_memory` (bytes), not `total_mem`. The typo crashed the
service immediately at startup because `get_model_info()` is
called from the FastAPI lifespan handler, not lazily — uvicorn
logged "Application startup failed" before any request could land.
Found while installing mana-video-gen on the Windows GPU box
(192.168.178.11:3026) for the gpu-video.mana.how Cloudflare route.
After the fix the service starts cleanly under the ManaVideoGen
scheduled task and responds 200 on /health both LAN and via
Cloudflare tunnel. status.mana.how now reports 42/42 — first time
ever.
