   • Still answer based on SKILL.md patterns + built-in knowledge
3. If reference file exists, incorporate its content into the answer

Key Patterns

1. Basic Layout Container

<View> {
    width: Fill
    height: Fill
    flow: Down
    padding: 16.0
    spacing: 8.0

    <Label> { text: "Item 1" }
    <Label> { text: "Item 2" }
}

2. Centering Content

<View> {
    width: Fill
    height: Fill
    align: { x: 0.5, y: 0.5 }

    <Label> { text: "Centered" }
}

3. Horizontal Row Layout

<View> {
    width: Fill
    height: Fit
    flow: Right
    spacing: 10.0
    align: { y: 0.5 }  // Vertically center items

    <Button> { text: "Left" }
    <View> { width: Fill }  // Spacer
    <Button> { text: "Right" }
}

4. Fixed + Flexible Layout

<View> {
    width: Fill
    height: Fill
    flow: Down

    // Fixed header
    <View> {
        width: Fill
        height: 60.0
    }

    // Flexible content
    <View> {
        width: Fill
        height: Fill  // Takes remaining space
    }
}
