   Design notes
   - One accent colour (deep blue) taken from the ERP product itself, so the
     site and the software look like the same company.
   - System font stack: no webfont round-trip, which keeps Core Web Vitals
     healthy. Google weighs page speed in ranking.
   - Everything is fluid; the layout is CSS grid with minmax so it reflows on
     a phone without a single media query for the common cases.
