   Monochrome restoration: the original pre-redesign LYNX palette — six
   grayscale tones, no hue anywhere. Hierarchy and state are expressed
   through contrast and inversion, never color. The "primary" action is a
   light surface with dark text (inverted), not a colored button; the online
   dot, success, warning and destructive states are all derived from the
   same six tones. Design tokens here match source/admin-web/admin-web.css.
