Tools we run to verify quality — they don't ship in the app. Today we run these as a manual pre-push gate; automated CI is planned.

Accessibility

We build to WCAG 2.1 AA: semantic HTML, full keyboard operability, and labelled form controls. The comparison view never relies on colour alone — every lane pairs a hue with a shape marker — and offers a text-table equivalent of the visual. We're partially conformant with known gaps; read the full Accessibility Statement.
