Effective Web
Choose the route for the browser outcome and load only the references needed for the affected behavior. Use Design Planning for a new direction and Design Review and Modernization for a broad redesign; add focused routes as needed.
Work within the product language, supported browsers, and existing contracts. Preserve accessibility, privacy, authentication, and user data. Add states, fallbacks, fixtures, and tests for reachable behavior with meaningful user consequences; avoid speculative combinations.
Verify what the change can affect. Use browser evidence when rendering or interaction matters, and reuse existing fixtures and checks where sufficient. Complete authorized implementation and verification before handing back the result; report material evidence gaps.
