Critical Rules

View{ flow: Down Label{text: "Invisible"} }

// CORRECT
View{ height: Fit flow: Down Label{text: "Visible"} }

2. new_batch for Colored Containers with Text

// WRONG - text behind background
RoundedView{ draw_bg.color: #333 Label{text: "Invisible"} }

// CORRECT
RoundedView{ new_batch: true draw_bg.color: #333 Label{text: "Visible"} }

3. Named Children with :=

// Named (addressable, overridable)
title := Label{text: "Hello"}

// Static (not addressable)
Label{text: "Hello"}

4. Label Default Color is White

// Default text is white (#fff) - set color for light backgrounds
Label{text: "Dark text" draw_text.color: #333}

5. MapView MUST Have Fixed Height

// WRONG
MapView{ width: Fill height: Fill }

// CORRECT
View{ new_batch: true width: Fill height: 400
