Implements issue #5. Off by default; set LIVEVIEW_KEY in .env to enable. No JWT required — key-based auth via ?key= query param. Returns 403 when disabled or key is wrong. Read-only ReactFlow canvas (pan/zoom, no editing). Standalone mode loads from localStorage without a key. Includes 8 backend tests and 9 frontend tests.
