 /**
  * Whether a back affordance on the screen currently composing still leads somewhere.
  *
  * `false` on a destination sitting at the bottom of the back stack — every section the drawer and
  * the rail reset to. Their toolbars used to draw a back arrow regardless, which next to a permanent
  * drawer that already says where the user is reads as a second, redundant piece of navigation, and
  * which had nowhere to go: `AppNavigator.pop()` pops unconditionally, so the arrow's only effect on
  * a one-entry stack was to empty it.
  *
  * A screen reads this instead of reasoning about its own route, for the same reason it reads
  * [com.georgeci.moneysurfer.uikit.window.LocalSurferPane] instead of measuring the window: whether
  * back goes anywhere is a fact about the back stack, and only the navigation host knows it. See
  * `rememberBackNavigationNavEntryDecorator` in `:navigation` for where the value comes from.
  *
  * Defaults to `true`, so everything composed outside the navigation host — previews, component
  * tests, bottom sheets — keeps the affordance its caller asked for.
