A session unused for seven days is dropped, the Sessions list marks a day's idleness and
can sign all of those out at once. The hub keeps a KVM's own cookies from any browser that
has them and lends them to one that hasn't, on the wire and back to the page. The stack
editor and the new-stack dialog use CodeEditor: line numbers, YAML and .env colour under a
real textarea, Tab/Shift+Tab/Enter indentation, and a key bar on touch screens.
