# Hardware/software video encode (plan §7 / §W6): the per-vendor backends (NVENC, VAAPI, AMF, QSV,
# Vulkan-Video, PyroWave, openh264) behind one `Encoder` trait + `open_video` selector, extracted
# from the host so it depends on the shared frame vocabulary (pf-frame) rather than living inside
# the orchestrator. Speaks pf-frame (CapturedFrame/PixelFormat/dxgi identity) and pf-zerocopy
# (CUDA), never pf-capture — the capture→encode edge is one-way (plan §2.4).
