# Hearthwave — NVIDIA CUDA setup (build-from-source Docker path).  *** STUB ***
#
# This profile is scaffolded but NOT yet validated on an NVIDIA host. It mirrors
# setup-cpu.sh for dirs/config/models/voices and writes COMPUTE_BACKEND=cuda, but
# the GPU-acceleration path (NVIDIA Container Toolkit + STT final pass on CUDA)
# has not been tested. Validate on real NVIDIA hardware before relying on it.
#
# Prerequisites to wire before use:
#   - NVIDIA driver + NVIDIA Container Toolkit installed on the host
#   - `docker run --rm --gpus all nvidia/cuda:12.4.0-base nvidia-smi` succeeds
#
# Usage (after the above):
#   bash setup-cuda.sh
#   docker compose -f docker-compose.cuda.yml up --build
