Passing a deadline is not the end of accessibility work.
Products change. New components, copy, forms, embeds, documents and release paths can introduce regressions. A technically accessible workflow can become inaccessible after a redesign, plugin update, design-system change or content migration.

Accessibility belongs in design, development, QA, content, procurement and release management. The goal is not a one-time score; it is a product process that keeps barriers visible and fixable.
