62 letters and digits (A-Z a-z 0-9) rendered at 160px cap height on a 32x32 grid with 3px gaussian blur, combined with edge-orientation texture (15% weight). Scores are normalized so that 0 represents an average pair of fonts across the 1571 compared fonts, and 100 represents identical letter shapes. Computed on 2026-10-22 using glyph-shape + edge-texture v2.
