Review navigation landmark naming

there is one detail that makes the naming potentially complicated. we should try that the name used by sighted users to address the sidebar and top bar is in line with the one used in the aural interface. otherwise you get a tower of babel like problem, that screenreader users would search for "administrative sidebar" or "administrative top bar" in the docs with no luck or address those names in conversations for example on the drupal slack. plus navigation sidebar wouldnt necessarily ring a bell for screenreader users directly . and at the same time it is necessary to be mindful about the point @mherchel raised in #3452724-63: Navigation side bar and top bar should have appropriate aria labels

i agree that "Contextual administrative operations" would be a bit too verbose. i wonder, maybe positional language like sidebar and top bar is even unnecessary? how about something like admin navigation for the sidebar and context bar for the top bar? that way the label for the sidebar would be just admin (becoming admin navigation) and it wouldn't collide with the front end theme and context bar would be announced with "context bar, complementary"
