# Ollama, ROCm backend. Serves models on demand — safe to start before
# you've put anything in /models.
#
# Storage: Ollama's content-addressed blob store is bind-mounted under
# /models/ollama so all model data on the host lives under /models.
# Note: Ollama's blobs are SHA256-named, not raw GGUFs — llama.cpp/vLLM
# can't load them directly. Keep curated GGUFs at /models/<vendor>/...
# for those engines.
