   online-staff.css — the colleagues online, left of the global search (online-staff, decision 13 of 17/10)

   Loaded by the OnlineStaff component (HeadContent). Colours come from the --knm-theme-* tokens of knm-theme.css: no
   literal colour, so light/dark and the accent follow. Shown from 992px up (Bootstrap d-none d-lg-flex on the row).
