22/// Autocomplete-friendly alternative to [`rsx!`].
23///
24/// Uses standard Rust builder chains with `=> { children }` sugar:
25///
26/// ```ignore
27/// ui! {
28///     Frame::new().title("Panel").border(true) => {
29///         Text::new("Hello"),
30///         Button::new("Click").on_click(handler),
31///     }
32/// }
33/// ```
34///
35/// Everything before `=>` is a normal Rust expression (full autocomplete).
36/// `=> { child1, child2, ... }` desugars to `.child(child1).child(child2)...`.
