Canvas
- Root: <svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 21 21">.
- Keep the drawing inside a 15.24x15.24 live area: about 2.88 units of padding on every side (never less than 1).
- A typical icon's bounding box covers 48% of the canvas.
Drawing
- Outline icons: draw with strokes only and fill="none"; solid shapes are the exception.
- stroke-width="1".
- stroke-linecap="round", stroke-linejoin="round".
- Use fill-rule="evenodd" for holes.
- Round corners with a radius of about 2.
Geometry
- Put coordinates on whole or half units (72% integers, 15% halves).
- Straight lines: 78% horizontal or vertical, 16% at 45 degrees.
- About 42% of drawing commands are curves or arcs.
- Keep it simple: about 2 elements and 11 drawing commands per icon.
- Elements used by the set: path, g, circle.
Color
- Monochrome: paint with currentColor only, never a fixed color.
Output
- Reply with one complete <svg> element and nothing else: no comments, <title>, ids or scripts.
- Match the examples: reuse their shapes for shared parts (arrow heads, people, documents, badges).
