  Font: Plus Jakarta Sans
  Chosen over Geist (too developer-utilitarian) and Space Grotesk
  (too quirky/editorial) for its clean geometric proportions and
  just enough warmth to match the "conversational and confident"
  tone of a PM in gaming/tech. Works at all sizes and weights used.

  Plus Jakarta Sans is distributed as a variable font; one file covers

  latin-ext first (fallback), then latin (primary).
