ReLayer Puts React UI Inside Unity

Field notes

The workflow places an editable React/Vite application inside the Unity project rather than treating the interface as an externally managed web surface. During Play Mode, Vite development can provide HMR while Unity remains the authority for gameplay state; production output is refreshed into StreamingAssets before a player build. The Live Twin uses loopback-only transport, split browser and authority tokens, and a restricted action list, with source metadata such as src/components/ShopPanel.tsx:143:9 visible in the example.
