Design.

A deterministic 73-rule detector that reads your markup and names exactly how it looks generated: gradient-clipped headlines, fake dataviz, badge cards floated over the hero. It exits non-zero like it means it, and it catches tells that survive seven rounds of human critique. Skip its auto-fix; the check is the product.

A community catalog of one model’s design fingerprints: the teal accent, the blinking live dot, the container soup. Sharp as a mirror. It reads as a ban list, though, and designing by ban list alone leaves holes where the power was: better for seeing the tells than for writing a brief.

The cure for the same fifteen Google Fonts is looking at what real typographers actually set: in context, on real jobs, across a century. An archive, not a tool, and that’s the point: taste is calibrated on the genuine article, not generated from a prompt.

The production-test tells are the best part: “Jane Doe” casting, BETA pills in heroes, “scroll to explore” cues, 99.99% numbers. One catch: it’s genre-blind. A “Field Notes” label is costume on a SaaS page and native register on an outfitter site. Read it as advisories, not law.
