Static images don't show motion. You can't inspect real product structure. You don't see how interfaces evolve over time. You rarely understand what actually works in production. So I decided to go deep. I reviewed every major design reference platform I could find - not just the popular ones - and analyzed how they actually help in real-world work. The conclusion?
Design tokens are all your design decisions, that define a design system's aesthetic properties, everything from colors and font sizes to spacing units and border radii. They are the modern evolution of hard-coded values. They are stored in a central, platform-agnostic repository, establishing a single source of truth for your entire digital product suite. This central management allows teams to consume the exact same design values across all platforms (web, native apps, documentation).
Teams often use customer and user interchangeably until it breaks alignment. Here's how separating the two clarifies research, prioritization, and messaging across B2C, B2B, and B2B2C products.
