   KUFI-SQUARE.COM — Pixel Art / Square Kufi Design
   ============================================================
   Square Kufi IS the original pixel art (700 AD).
   Every design choice here reinforces that: sharp edges,
   grid alignment, no anti-aliasing, no curves, no gradients.
   The unit square is sacred.
