- vm_api.py: pure FastAPI JSON API on :8098 with CORS - vm-api.service: systemd unit for API (replaces inline HTML vm_web.py for frontend) - vm_web.py: kept intact as fallback; Apache now proxies /api/ -> :8098 - frontend/: Vite + React + TanStack Query scaffold - Apache vhost updated: DocumentRoot -> frontend/dist, /api/ proxy, SPA fallback - All original HTML pages still functional via :8099 during transition
