/* ==========================================================================
   Saizen Acuity — Aamar Hussain — "Agentic"
   Light and Google-born: white surfaces, Google's four colours (blue, red,
   yellow, green), soft Material elevation and generous rounding. Aamar builds
   agents, so the page runs on them: a live mesh of agents passing messages in
   the hero, his portrait in an agent workspace with a prompt that keeps
   asking, a multi-agent orchestrator you can run, and a token-economics
   model to close. Type is the site's: Playfair Display SC headlines,
   Playfair Display, DM Sans and DM Mono. Emphasis is upright colour.
