# Wizard Interface Redesign - Complete ✅

## Overview

The Wizard Interface has been completely redesigned to provide a cleaner, more focused experience that fits everything in a single window using a tabbed layout. The interface is now more compact and professional while maintaining all functionality.

## Key Changes Made

### 🎨 **Single Window Tabbed Design**
- **Replaced**: Multi-section scrolling layout with sidebar
- **With**: Compact tabbed interface using `Tabs` component
- **Result**: All content accessible without scrolling, cleaner organization

### 📏 **Compact Header**
- **Removed**: Large EntityViewHeader with redundant information
- **Added**: Simple title bar with essential info and controls
- **Features**: 
  - Trial name and participant code
  - Real-time timer display during active trials
  - Connection status badge
  - Action buttons (Start, Next Step, Complete, Abort)

### 🏷️ **Tab Organization**
The interface now uses 5 focused tabs:

1. **Execution** - Current step and action controls
2. **Participant** - Demographics and information  
3. **Robot** - Status monitoring and controls
4. **Progress** - Trial timeline and completion status
5. **Events** - Live event log and history

### 🎯 **Button Improvements**
- **Changed**: Full-width buttons to compact `size="sm"` buttons
- **Positioned**: Action buttons in header for easy access
- **Grouped**: Related actions together logically

### 🎨 **Visual Cleanup**
- **Removed**: Background color styling from child components
- **Simplified**: Card usage - now only where structurally needed
- **Cleaned**: Duplicate headers and redundant visual elements
- **Unified**: Consistent spacing and typography
