/// <summary>
/// Somebody's own engine: Ollama, LM Studio, vLLM, llama.cpp, llmman, or a proxy in front of them.
/// </summary>
/// <remarks>
/// vLLM serves whatever it was pointed at, and what it was pointed at is usually a hub repository:
/// "meta-llama/Llama-3.3-70B-Instruct", "01-ai/yi-large". So the organization comes off here too.
///
/// llmman goes one further and names the registry it pulled the model from:
/// "hf.co/unsloth/Qwen3.5-0.8B-GGUF:latest", "docker.io/ai/qwen3.5:0.8b". The registry is one more
/// path segment and comes off the same way, one segment at a time.
///
/// The colon does not. Ollama writes the variant after it -- "qwen3.8:27b-mlx" -- and taking that
/// off would leave a name which no longer says which build of the model is running. Only the host
/// which actually has a router treats a colon as routing.
///
/// Whatever the engine can do beyond this, only the engine knows: how large a context window the
/// operator configured, how many images it accepts. Those come from the model list of the running
/// installation, not from a rule written here.
