   Saizen Acuity · Kumar Chetan · "Scale at speed"
   Light, in Tech Mahindra's colours: warm cream and white, a confident red,
   deep navy ink, and a calm deep teal that carries the interface so the red
   stays a brand mark and a risk signal. Crisp by design: hairlines instead of soft shadows, 4px
   corners, no glows or glass. The architect's language runs through it: a
   drawing sheet with dimension lines and a title block, an ADR, a
   traceroute of his career, a telco blueprint you can modernise, and a data
   centre migration you can run. Type is the site's: Playfair Display SC
   headlines, Playfair Display, DM Sans and DM Mono.
