Component-driven Design System Architecture

Challenge summary

Design a component system that gives product teams consistent accessible behavior while themes, direction, packages, and APIs evolve safely.

What you'll practice

• Separate primitive values, semantic tokens, themes, and text direction.
• Specify component behavior with native semantics and pattern-specific keyboard rules.
• Package public entry points for selective consumption and verify real bundle output.
• Treat metadata as documentation input, not proof of runtime accessibility.
• Roll out breaking changes with compatibility tests, prereleases, and migrations.

What Premium unlocks

Premium unlocks the layered architecture, public contract model, compatibility worked example, governance decisions, and release safeguards.
