Two conflicts, both unions of independent removals/fixes: main fixed the same three install.rs SAFETY comments this branch fixed (main's phrasing kept), and the runner provisioning drops BOTH env lines — main removed PF_FFVK_VULKAN_INCLUDE (pf-ffvk is gone since the FFmpeg replacement), this branch removed VBCABLE_DIR (the retirement).
