/* <UserMenu> — same header icon-button + popover chrome as
   `LinksMenu`/`SettingsMenu`, except the trigger is a round, accent-
   coloured initials avatar rather than a glyph-on-transparent button —
   this is the "who is this" affordance, the other two are quiet chrome.
   Kept as its own stylesheet for the same reason `SettingsMenu.css`
   gives: three small, independently-evolving popovers that happen to
   look alike today, not one component with three skins. */
