   Saizen Acuity · Balachandar Mani · "Signal from noise"
   Dark, in Northern Trust's forest greens, lit like an analytics terminal:
   mint for data, gold for insight, coral for exceptions. The hero is a live
   data terrain; the at-a-glance is a query that runs; the career is a
   dataset you can sort; Skanda Security decrypts itself; the starring
   simulation finds real exceptions in seasonal asset-servicing data; and
   the education is a learning curve. Type is the site's: Playfair Display
   SC headlines, Playfair Display, DM Sans and DM Mono.
