💡 n.p.: I'm curious if you considered avoiding wrapping ProductInfo with Box. For example, can we introduce modifier: Modifier = Modifier arg in ProductInfo composable, and pass a Modifier with some matching state (.fillMaxWidth() maybe)? I didn't dig deep enough to be sure this would be a good solution here; it just caught my attention that we can try making ProductInfo component configurable with Modifier instead of wrapping it.
