   VIVEK KAUSHIK — PORTFOLIO
   Design concept: the page presents itself like a design-tool canvas
   (Figma/Adobe XD) being inspected — dot-grid canvas, selection handles,
   spec-tag annotations, a live x/y coordinate readout, and project cards
   framed as browser windows. Pink is the "selection" accent color.
