# visionA-local — Makefile（骨架，M1-1）
#
# 這份 Makefile 目前所有 targets 都只是 placeholder，實際內容會在後續任務逐步填入：
#   - M1-2  複製 server core
#   - M1-4  複製 frontend
#   - M1-8  build-server / build-frontend 實作
#   - M1-9  visiona-local (Wails) shell
#   - M1-11 payload-macos
#   - M1-12 installer-macos (dmg)
#   - M2+   Windows / Linux / CI
#
# 詳見 .autoflow/04-architecture/build-pipeline.md
