- Use provider model ID "Qwen/Qwen3.5-27B", not the LLMReference slug "qwen3.5-27b".
- Use exact Featherless catalog id in modelProvider.providerModelId (HF-style org/name). Not interchangeable with LLM Reference slugs.
- The examples expect FEATHERLESS_API_KEY; rename it only if your application config maps the new variable.
