## Summary

Reusable tokens and components should make repeated interface decisions consistent while still
allowing intentional exceptions.

## Deep Guidance

Compare repeated colors, spacing, typography, buttons, form controls, and state treatments for
unexplained variation. A design-system finding is strongest when it identifies a repeated pattern
that has drifted from the apparent token/component set, not when it merely dislikes a style.
Recommend consolidating to an existing token or component, documenting an intentional exception,
or introducing a named reusable decision when the same local override appears in multiple places.
