+# Examples
+
+The repository has five current experiences. Images below use the examples' existing captured assets—there are no documentation copies.
+
+## Minimal

+
+## Color Balance

+
+## Live composition

+
+## Multi-view
+
+![One shared graph rendered in two independent canvas views](../../../examples/assets/multi-view.png)
+
+_One worker and graph with independent cameras and selections. The application-owned toolbar targets the active view, and the canvases forward pointer events only. [Source](https://github.com/Heaust-ops/fxnode/blob/main/examples/multi-view/main.ts)._
+
+## Blender-shaped gallery
+
+The [larger gallery source](https://github.com/Heaust-ops/fxnode/blob/main/examples/blender/main.ts) exercises many node and interaction shapes; it is repository application code, not package authority.
+
+These examples present and persist editable graphs; they do **not evaluate** them. Blender-shaped fixtures and visual regression images do not establish Blender compatibility, behavioral parity, or pixel parity.
