Stroke Weight, Grid Systems, and Icon Scalability

To feel part of a unified family, icons in a design system must share strict structural constraints:

• Base Grid: Typically constructed on a 24x24px or 20x20px canvas with a 2px interior padding boundary.
• Uniform Stroke Weight: Icons must share a consistent line weight (e.g., 2px strokes with rounded terminals).
• Style Cohesion: Never mix outlined (linear) icons with filled (solid) icons within the same navigation level, unless filled is used intentionally to denote the active/selected state.
