# The Linux GPU zero-copy plumbing (plan §9 / §W6), extracted into a leaf crate so the shared
# frame vocabulary (pf-frame `FramePayload::Cuda`), the encode backends (CUDA copies/context),
# and the capture import machinery can all reach it WITHOUT the host orchestrator in between.
# Content is Linux-only; the crate compiles to an empty lib elsewhere so dependents can carry a
# plain (non-target-gated) dependency.
