/* ============================================================================
   profile-button.css — dedicated profile button + popover
   ============================================================================
   Renders next to the messages/invitations buttons inside .header-tray--icons.
   Clearly signals signed-in vs signed-out at a glance via:
     - an ambient status dot (green = signed in, muted = signed out, amber
       pulse = authenticating, red = error)
     - an avatar circle (photo or initials) when signed in, a person glyph
       when signed out.

   Also renders a small popover below the button with identity details and the
   sign-in / sign-out action so it feels like a dedicated surface, not a
   tooltip.
