Give my app a baseline accessibility pass before launch. 1. Automated scan: add axe-core (via axe-playwright, cypress-axe, or the integration for my test runner) to my test suite and run it against my key pages: landing, signup, login, the main app screens, and checkout. Fail the build on critical violations. 2. Keyboard walkthrough: manually walk the core flows (signup, login, main create/edit action, checkout) using only the keyboard. Fix what breaks: elements that cannot be reached by Tab, actions that only work on click, focus that disappears into hidden elements, and modals that do not trap and return focus. 3. Quick wins audit: check the high-frequency violations across all pages: every form input has an associated label, every image has meaningful alt text or an empty alt for decorative images, color contrast on body text and buttons meets 4.5:1, and page language is set on the html element. 4. Focus visibility: make sure focus indicators are visible; if a CSS reset killed outline, restore a styled one instead of leaving keyboard users blind. 5. Error accessibility: form errors must be announced to screen readers (aria-live or associating the error with the input via aria-describedby), not just red text. Do not attempt a full WCAG certification pass; this is the baseline that catches the violations real users hit first. Do not change the visual design except where contrast fails. Give me: the axe integration code, the list of violations found and fixed per page, and the results of the keyboard walkthrough per flow.
