Most component systems fail because they are documented like catalogs, not built like operating systems. Teams need rules, not just screenshots.
A resilient system defines constraints early: spacing rhythm, hierarchy tokens, and state behavior. Once these are fixed, teams can scale pages without visual drift.
I also separate foundational components from campaign-specific patterns. This keeps the core stable while still allowing creative flexibility where needed.
When done right, teams move faster because decisions are already encoded in the system.
