   Homepage live-state visual contract

   JavaScript owns semantic state and dynamic text. This stylesheet owns all
   state-dependent colour, halo, animation, and control presentation. State is
   intentionally component-scoped so nav health, deployment, backend services,
   countdown activity, and registry freshness can disagree honestly.
