- Straight lines: 58% horizontal or vertical, 14% at 45 degrees.
- About 55% of drawing commands are curves or arcs.
- Keep it simple: about 2 elements and 28 drawing commands per icon.

Color
- Monochrome: paint with currentColor only, never a fixed color.
- Duotone: add a second layer of the same color at opacity .3 to .4 (100% of icons).
Output

- Match the examples: reuse their shapes for shared parts (arrow heads, people, documents, badges).
