# Architecture: Neuro-Adaptive UI

## Data Flow
1. **Data Acquisition:** `MNE-Python` simulates raw 14-channel EEG streams.
2. **Feature Extraction:** Power Spectral Density (PSD) analysis isolates Alpha/Theta ratios.
3. **Decision Engine:** Random Forest Classifier determines cognitive state (Low/Medium/High).
4. **Adaptive UI:** WebSocket server triggers UI theme/density shifts in React.
