/* ==========================================================================
   Upgrad — case study (Career Centre, 2021)
   Loads after site.css (tokens, nav, footer, project intro, button).

   Typography follows the site system:
   · serif (Light 300) only for the voice — the headline, chapter and section titles, the reflection
   · sans 400 to read and navigate · 500 to press · 600 tracked tight to scan and choose
   · the product UI keeps upGrad's own face (Lato), like the Google demo keeps Sobi's
   Layout and motion are the case study's own: a pinned first fold where product fragments dock
   into a vector dashboard, a research viewer, and four pinned design chapters.
