 # Image variant. Two choices:
-#   cpu — works on any host. Kokoro is tiny (82M params) so CPU
-#         inference is acceptable: TTFA ~1s on a modern CPU vs
-#         ~300ms on a 30-series-or-newer GPU. Fine as a default.
-#   gpu — requires NVIDIA driver supporting CUDA >= 12.9. As of
-#         2026-04-25, irv-ml1's driver 570.124.06 caps at CUDA 12.8,
-#         so the gpu variant won't start there yet. Bump the driver
-#         (separate procedure, requires reboot) then flip this to gpu.
