15/// Node that stores text content and handles measurement, drawing, and semantics.
16///
17/// This node implements three capabilities:
18/// - **Layout**: Measures text and returns appropriate size
19/// - **Draw**: Supplies prepared text state consumed by scene building
20/// - **Semantics**: Provides text content for accessibility
21///
22/// Matches Jetpack Compose: `TextStringSimpleNode` in
