panel_helpers.rs

1//! Utility methods for finding and toggling specific sub-panels.
2//!
3//! These helpers iterate over all panel lists (left, right, bottom, detached,
4//! empty) to locate a panel by its concrete type and modify its visibility state.
5//! They are used by the controller modules and the layout/rendering code.
