/**
 * #67 — a name is not a link on a phone, and the menu is where it went.
 *
 * The queue panel is the surface this is visible on: its rows draw a
 * track title and an artist credit as `explore-link`s at every width,
 * unlike `track-list`, whose phone column set stacks title over artist
 * as plain text already.
 *
 * **The pair is what makes either assertion mean anything.** A link
 * that is gone and a menu item that never arrived is not a smaller
 * affordance — it is a destination the phone cannot reach, which is
 * what plan 018's "no action is unreachable at any supported size"
 * refuses. So each test asserts the phone and the desktop in the same
 * breath: text *and* an item here, a link *and* no item there.
 *
 * The desktop half is also the regression guard for the change: menus
 * above the breakpoint must be exactly what they were, because the name
 * beside them is still a link and a menu that repeats the row is
 * furniture.
