//! The **role strip** (§9.4) — which role the pane's two dropdowns are
//! changing at all.
//!
//! Its own file beside [`super::select`] at §12's cap, on the seam that file's
//! own doc already draws: the pair row is a *row* (two dropdowns and a
//! separator, chosen where they are read), and this is the **scope** over it —
//! painted in the pane because a row cannot hold it, and choosing here writes
//! nothing (bl-fb6b). Coverage-excluded glue like the rest of `src/shell/*`.

/// special case), painted in the pane because a row cannot hold it. It defaults
/// to the role that talks to you; a role whose model is unusable carries the
/// warning glyph, its reason painted below. Choosing another role **re-scopes
/// the row's two dropdowns** onto that role's own assignment — the strip is the
/// scope, not an action (bl-fb6b), so there is no per-role apply.
