*	tools/lg: v2 demo-video composition scripts (split-screen + card builder)	Arthur Hanson Rasmusson	16 hours
\| \| \| \| \| \| \| \| \| \| \|	split_screen.sh composes two guest frame streams (KVMFR PPMs from frame_reader.py) into one hstacked mp4 with last-frame padding for unequal lengths; build_video.sh wraps a title card, the main segment and an end card (drawtext, detected font) into the deliverable mp4. Both verified end-to-end with synthetic PPM sequences (ffprobe: 1280x720 h264, padding pixel-exact). These are the capture-side pieces for the 1.0.0 video; the guest-side publishers are tools/guest-diag/xshm_pub.c (X screen) and the existing frame_producer; the host reader is tools/lg/frame_reader.py.

	Looking Glass status - tools/cuda-ab/frame_producer.cu: renders an animated Julia frame on the guest GPU and publishes it into the ivshmem BAR (the kvmfr 128 MiB window) with a small header + RGBA payload. - tools/lg/frame_reader.py: host-side reader of /dev/shm/kvmfr-<uuid> that saves each published frame as a PPM (the transport half of the frame path). - tools/guest-diag/egl_frame.c: EGL probe (device/surfaceless/default platforms) - live result: eglQueryDevicesEXT sees the NVIDIA device and eglInitialize succeeds, but eglMakeCurrent fails EGL_BAD_ALLOC (0x3003), the same VASpace-allocation wall as Xorg's 'Failed to allocate VASpace object'. - docs/05-operations/06: the state, the blockers and the exact remaining pieces (guest GL VASpace allocation; LGMP session producer).
