/* EngNet Portal — built on the EngNet design system (EngNet brand: copper on cool neutrals).
   Borders, not shadows. Near-square corners. Archivo for headings, IBM Plex Sans for text,
   IBM Plex Mono for labels, IDs, hostnames and every number that lines up.
   Layout: a header band, then one content column (customer) or rail + workspace (admin). */
