/*
 * CN-09 Settings sub-nav — app/components/ui/settings_sub_nav_component.rb
 *
 * "One partial, two renderings" (same mechanism as DD-01 table.css): both
 * the 44px row list and the CN-08-style pill bar render server-side. Spec
 * §3.4 CN-09 line 524: "Below --bp-lg it becomes CN-08" — that --bp-lg
 * (1024px) is the VIEWPORT, not the component's own width (in real use
 * the sub-nav sits in a ~240px sidebar column, which never reaches 1024px
 * regardless of viewport, so a container query on the component's own
 * width would never switch to the list rendering — dead code). The switch
 * is a plain viewport media query; `.is-pills` is a forced class for the
 * styleguide's narrow-demo screenshot, which fakes the collapsed state
 * without pretending a narrow wrapper means a narrow viewport.
