+# Infinity Mirror Control
+
+V1 desktop control app for a 3x6 Infinity Mirror tile grid with a strong preview, XML mapping editing, presets, and an extensible output layer.
+
+## Launch
+
+```powershell
+python -m app.main
+```
+
+The app will try to open the bundled sample mapping from `sample_data/infinity_mirror_mapping_clean.xml` on first launch.
+
+## Architecture
+
+- `app/config`: XML parsing, validation, and config models
+- `app/core`: shared types, colors, presets, and the render controller
+- `app/patterns`: pattern definitions and registry
+- `app/output`: preview and hardware output backends
+- `app/ui`: Qt widgets, settings editor, preview, and main window
+
+## Notes
+
+- Live output is disabled by default for a safe startup state.
+- The Art-Net backend is prepared as an extension seam and can be expanded later without refactoring the UI or pattern engine.
+- Unit tests cover config parsing, round-tripping, and core pattern rendering without requiring Qt.
+- The app prefers `PySide6`, but falls back to `PyQt5` automatically when the local Qt6 runtime is broken or unavailable.
