/* ==========================================================================
   Saizen Acuity — Sudip Roy — "Evidence"
   Lanthra's world, in the dark: deep ink, teal for what is structural,
   clay for what is controllable, amber for what needs a look. Sudip founded
   Lanthra, so the page reads like its engine: expected versus actual. The
   hero is a live benchmark of 317 points around a match line, his portrait
   sits in a Lanthra window, and the close is a Pulse readiness radar.
   Shared systems are adapted from the Wael profile; type is the site's:
   Playfair Display SC, Playfair Display, DM Sans, DM Mono.
