//! Accessibility of the app's own controls.
//!
//! The shared widgets in `widgets.rs` are raw `ui.interact` rectangles. Without a `WidgetInfo`
//! they are not in the accessibility tree at all, so neither a screen reader nor kittest can
//! reach them; and an input control without a name is unreachable even when it is in the tree.
//! `Harness::run` checks the tree it has, but only for the screen it settled on: this opens every
//! panel and checks again.
//!
//! Limit: a control that reports no `WidgetInfo` at all has no node, so it is not "unnamed" here.
//! `widgets::checkbox` and the raw-painted row controls (`icon_toggle`, `scroll_bar`, hot-number
//! values) are still in that state; naming every call site is separate work.
