[perf] H3 decode: pin the frozen VAEs' host copies
...
With the device-to-host copy gone, the remaining host-to-device copy is the
stage's cost, and from pageable memory it is staged through a bounce buffer at
roughly 2.6 GB/s instead of full PCIe speed. The host copies are made once, so
pinning them costs nothing per request.
It does cost the module's size in non-pageable host memory (10.4 GB for the
H3 video VAE, 0.6 GB for the audio VAE, per rank) for as long as the pipeline
is alive. It follows --pin-cpu-memory, which is on by default; --no-pin-cpu-
memory keeps the copies pageable and only loses the bandwidth. Note that this
flag did not already reach the VAE: its other use is FSDP's own CPUOffloadPolicy
and the VAE does not go through FSDP.

[perf] H3 decode: offload the frozen VAEs without the device-to-host copy
...
The decode stages move the 10.4 GB fp32 video VAE (and the 0.6 GB audio VAE)
with module.to(device) / module.to("cpu") on every request. The weights are
frozen -- the whole stage runs under no_grad -- so the copy back to the host
returns bytes the host already has.
Keep one host copy per tensor, made the first time the module is loaded, and
on unload point .data back at it instead of copying. One H2D per request, no
D2H at all; the module still lives on the host between requests. Where the old
path allocated a fresh host tensor per cycle and freed the previous one, this
reuses one buffer, so peak host memory can only go down.

[bugfix]: allow MiniMax H3 frame padding at the 15-second limit
...
Accept the causal-VAE-aligned 362-frame bucket (15.083 s) for 15-second H3 requests.
- Hoist MINIMAX_H3_MIN/MAX_ALIGNED_FRAMES next to align_num_frames and reuse them in the CUDA stage, the MLX runtime, and the LoRA example so the bound is consistent across entry points.
- State the accepted frame range in the error messages.
- Cover seconds="15" -> 362 at OpenAI admission and the MLX resolve_geometry bound.
- Update the Spark/openai cookbook frame caps from 345 to 362.
Known gaps: no GPU-lane coverage for the 362 bucket (SSIM runs 124 frames; the golden gate is a fixed-geometry fingerprint), and explicit num_frames=360 still hits the pre-existing grid gate.
