//! InputCoordinator registration helper for text input widgets.
//!
//! `register` is the one-call entry point a widget owner uses every frame
//! to:
//! - declare the atomic widget (`WidgetKind::Custom` for now — `TextInput`
//!   should be added to `WidgetKind` in a follow-up pass),
//! - tell the coordinator about the field's `TextFieldConfig` so char/key
//!   events get routed correctly while the field is focused.

/// for keying its row in `TextFieldStore`).

    // with `state::TextFieldConfig` (which is a copy), the caller is expected
    // to invoke `register_text_field` directly with the canonical type.
