# ============================================
# CLIProxyAPI Plus - Hugging Face Spaces Dockerfile
# ============================================
# 此 Dockerfile 專為 HF Spaces 設計
# 
# 運行模式：
# 1. 完整模式（Go + Streamlit）：需要預先構建 CLIProxyAPIPlus 二進制
# 2. 僅 Streamlit 模式：不需要 Go 二進制，僅運行前端 UI
#
# 構建 Go 二進制（在專案根目錄執行）：
#   GOOS=linux GOARCH=amd64 go build -o hf-spaces/CLIProxyAPIPlus ./cmd/server/
# ============================================
