/* ============================================================================
   Intelligence Ops (admin) — design system, ported verbatim from
   docs/admin_pages_mockup.html and scoped under #page-admin so the mockup's
   generic class names (.page, .section, .kpi, .pill, table.t, .tab, …) cannot
   collide with the rest of the app. Design tokens hang off #page-admin, not
   :root, for the same reason. This file is the single source of the exact UI.
