White-Label Design Systems: Empowering B2B Customers

In white-label B2B SaaS, enterprise customers demand the ability to upload their own logos, primary colors, and custom fonts.

A robust design system restricts white-label customization to a safe customization surface:

Customers may override semantic brand tokens (--brand-primary, --brand-secondary).
Customers cannot override structural layout tokens (margins, paddings, z-index, interactive hitboxes) that would break usability or cause UI regression overlaps.
