Opt-in NVIDIA_UNIVERSAL lane (default NO; normal/single-branch builds unchanged):
one ISO that adapts to an unknown NVIDIA target.
- build.cfg: NVIDIA_UNIVERSAL flag.
- build.sh: install_nvidia_universal_repo() stages an on-image pkg repo with all
three branches (390/470/580 + settings), pkg-repo metadata, and a file:// repo
conf; universal mode bakes no branch and sets clawdie_live_gpu_mode=nvidia-auto.
- clawdie_live_gpu: nvidia-auto mode detects the device id (PR #30 fix) -> branch
{390,470,590} -> pkg-name -> `pkg install -r clawdie-nvidia` -> kldload, all
best-effort with fallback to integrated/scfb (never blocks boot).
- doc/NVIDIA-UNIVERSAL-HANDOFF.md: Codex FreeBSD build + hardware validation plan.
sh -n clean; detector+branch+pkg map unit-tested on Linux
(1c8c->590->nvidia-driver-580, 0fc8->470, 0e22->390). The pkg fetch/repo layout,
offline boot install, writable root, kernel ABI, and image size MUST be validated
on the FreeBSD build host + real NVIDIA hardware (see handoff).
