• 28+ packages organized by responsibility
• 35+ widgets with consistent patterns
• Sub-cell graphics using Braille/Sextant/Quadrant rendering
• Reactive state via signals and computed values
• Two backends: tcell (terminal), sim (testing)
• Built-in accessibility with screen reader support
• Agent integration via MCP protocol

Go Version: 1.24+
