/**
 * Extracts text-specific styles from a combined style object.
 * Useful when you need to apply text styles to a Text component
 * from a style object that may contain View styles.
 *
 * @param style - The combined style object to extract from
 * @returns A new object containing only TextStyle properties
 *
 * @example
 * ```ts
 * const combinedStyles = {
 *   backgroundColor: "#fff",
 *   padding: 16,
 *   color: "#000",
 *   fontSize: 14,
 *   fontWeight: "600",
 * };
 *
 * const textStyles = composeText(combinedStyles);
 * // Result: { color: "#000", fontSize: 14, fontWeight: "600" }
 *
 * // Usage in components
 * <View style={combinedStyles}>
 *   <Text style={composeText(combinedStyles)}>Hello</Text>
 * </View>
 * ```
