   KARABO SISHUBA — PORTFOLIO STYLESHEET

   Design concept: a working research notebook. Karabo's background is
   Economics before it was code — this reads like an annotated manuscript,
   not a SaaS dashboard. Paper, ink, a rust-red marginalia accent, serif
   headings, monospace for data and labels, flat surfaces and hairline
   rules instead of rounded cards and shadows.
