   Subject: Acceptance fixture for publishing throughput. Minimalist, direct, accessible single-action page.
   Palette: Stark slate ink on clean neutral ground with high-contrast cobalt accent.
   Typography: Clean system neo-grotesque sans stack.
   Device: Pure functional layout with a single working action button and status indicator.
