   TOGETHER TRACKING — primitive kit (Executive Command)
   Buttons, topbar/nav, cards, chips, inputs, modal.
   Component looks lifted from Catalyst so the two surfaces are one family;
   every primitive consumes --c-* tokens + the brand set, so it renders on
   paper or navy and under any tenant theme.
