Struct TreemapState 

pub struct TreemapState {
    pub hover: Option<usize>,
}

Persistent, observable interaction state (FC-3): the original tile index the pointer last hovered. Serialized so it round-trips headlessly.

Fields

hover: Option<usize>

The hovered tile’s original index (into tiles), or None.
