+# RuView — Live 3D Point Cloud Viewer
+
+Hosted at: https://ruvnet.github.io/RuView/pointcloud/
+
+## Modes
+
+- Default — synthetic in-browser demo (no backend, no network calls).
+- `?backend=auto` — fetch from `/api/splats` on the same origin
+  (only works when the viewer is served by `ruview-pointcloud serve`).
+- `?backend=<url>` — fetch from `<url>/api/splats`. The intended
+  local-ESP32 use is `?backend=http://127.0.0.1:9880`: run
+  `ruview-pointcloud serve --bind 127.0.0.1:9880` on the same
+  machine with your ESP32 streaming CSI to UDP port 3333, then
+  visit the URL above. The local server's CorsLayer permits
+  requests from `https://ruvnet.github.io`, and modern browsers
+  permit HTTPS→127.0.0.1 mixed-content as a trustworthy origin.
+  The "📡 Connect ESP32" button in the viewer prompts for this
+  URL and persists it in localStorage.
+- `?live=1` — require a live backend; show an offline message instead
+  of falling back to the synthetic demo.
+
+See ADR-094 for the deployment design.
