This project started from a common pain point:
even with a solid design system document, style drift appears quickly if there is no automated auditing.

Goals

detect token mismatches (color, spacing, typography),
surface component-level styling escapes,
generate readable reports for designers and engineers.

Core Approach

1) Token Registry Mapping

The tool loads approved token values and builds an allow-list index.
Any unregistered value is flagged as a potential inconsistency.

2) Style Scanning

It scans CSS, inline styles, and theme variables for:

non-standard color literals,
unapproved type scales,
spacing values outside agreed steps.

3) Severity Levels

Audit output is grouped by:

error for hard-rule violations,
warn for convergence suggestions,
info for trend visibility.

Practical Benefits

faster visual regression checks for new pages,
less screenshot-only review overhead,
clearer evidence for why a style is considered off-system.

Next Steps

add Figma token import adapters,
integrate with CI to block high-risk violations,
provide page-level visual diff support for faster fixes.
