Every finding carries the element it came from, the value it measured, and the one token that would fix it.

One pass, four moves

Read the page, hold it against the contract, recompose what drifted, and file every step of it.

Read the page

It opens the URL in a real browser, walks the rendered DOM, and records the computed value of every element it meets.

The contract

Your tokens, your ratios, your spacing steps. The contract lives as a file in your repo, and every scan reads it.

Recompose

Where a value drifted, it names the token that belongs there and shows both, so you approve a swap.

A second opinion: The scan reads your page the way a design lead would, then names what it would change.
No design hire: You get the review before the launch, not the apology thread three weeks after it.

It found nine grey values on a page we had already signed off. Not opinions - the computed values, listed.

The findings come back as token swaps. I read them in a pull request instead of a comment thread.
