            ## Portable bundle (standalone, ~1 GB)

            Lux + luxd + llama-server + pre-downloaded `henrywangxf/lux` weights (Q4_K_M GGUF) — extract and run, no system install or network required.

            **Download:** https://huggingface.co/henrywangxf/lux-portable/resolve/main/lux-portable-linux-x86_64-${{ github.ref_name }}.tar.gz

            ```
            tar xzf lux-portable-linux-x86_64-${{ github.ref_name }}.tar.gz
            cd lux-portable-linux-x86_64/
            ./lux
            ```

            ## Raw binaries

            Attached below. Requires an existing OpenAI-compatible LLM server (Ollama or llama-server); see the repo README for install steps.
