   Kishor Insights — Material tiles edition
   A tinted-white, tile-and-elevation take on the same Kishor Insights
   content: Material Design 3 color roles (primary/secondary containers,
   tonal surfaces), an elevation-shadow scale instead of borders, rounded
   "tile" corners, and Poppins/Roboto in place of Oswald/Inter. No JS —
   the projects list uses a CSS-only radio/label tab switch and the two
   galleries are native horizontal scroll-snap strips.
