/* ==========================================================================
   PORTFOLIO — PREMIUM ENGINEERING PRODUCT SITE
   Design language: Vercel/Linear/Stripe-grade SaaS, tuned for an infra
   engineer. Signature idea: this person's work is measured in numbers —
   uptime %, MTTD minutes, module counts — so every metric in the page
   (stat numbers, achievement numbers, skill %, dates) renders in a
   monospace face, like a dashboard reading out real telemetry. Everything
   else (headings, body copy) stays humanist and quiet around it.
