Deck

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

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

Every pass lands in the catalogue with its score, its findings and the diff, so the next reader starts from the record.
