   Laurus Operating System (LOS) - los.laurusgroup.co.uk
   Standalone product site design system. Premium enterprise technology
   feel: dark, clean, modern, navy + gold (matching LOS's own established
   mark and losportal.com), IBM Plex Sans/Mono. Deliberately all-dark
   throughout (no light/white sections) - the previous company-style
   homepage this site replaces mixed light and dark sections; this is a
   different brief (a standalone LOS product site), not a restyle of that
   page, so the whole page now reads as one consistent dark surface.
