+The safe area maximum insets are four [=environment variables=]
+that are tied to the <a href="#safe-area-insets">safe area inset variables</a>.
+Unlike the safe area inset variables which are dynamic values,
+the safe area maximum insets are static values
+that represent the maximum value of their dynamic counterpart
+when dynamic UA interfaces are retracted,
+making the [=layout viewport=] size the [=large viewport size=].
