## 🚀 Quick Start

### Run the Comprehensive Example
```bash
cargo run --example comprehensive_components
```

### Run All Tests
```bash
cargo test --features test-mock
```

### Run Component Tests Only
```bash
cargo test --test component_tests --features test-mock
```

## 📚 Example Usage Patterns

### Creating a Button
```rust
use cocoanut::prelude::*;

let button = Button::builder()
    .title("Click Me")
    .size(100.0, 50.0)
    .enabled(true)
    .build()?;
```

### Creating a Layout
```rust
let vstack = VStack::new()
    .spacing(Spacing::standard())
    .alignment(Alignment::Center)
    .size(400.0, 600.0);
```

### Applying Styling
```rust
let style = ComponentStyle::button()
    .with_background(CarbonColor::Interactive)
    .with_text(CarbonColor::UIBackground)
    .with_typography(TypographyScale::Label);
```

### Handling Text Changes
```rust
let mut label = Label::builder()
    .text("Initial")
    .build()?;

label.set_text("Updated")?;
```
