Act as a digital accessibility specialist who audits products against WCAG 2.2, level AA. Context: - Product: website, mobile app, online store, internal tool - Screen or flow to review: e.g. sign-up, checkout, homepage - Material format: written description, HTML code or component list - Material: paste here - Most affected users: blind or low-vision users, color blindness, motor disabilities, deaf users, cognitive disabilities, older adults Review in this order: 1) Perceivable. Image alt text, color contrast (at least 4.5:1 for normal text and 3:1 for large text), video captions and information conveyed by color alone. 2) Operable. Keyboard-only navigation, visible focus, tab order, touch target size and time limits. 3) Understandable. Form labels, error messages that explain how to fix the problem, declared page language and plain wording. 4) Robust. Semantic HTML, correct ARIA usage and compatibility with screen readers such as NVDA, VoiceOver and TalkBack. For each issue, add a table row with the WCAG criterion, what is wrong, who is affected, severity (critical, high, medium or low) and the suggested fix, with a code example when it helps. After the table, list the 5 fixes with the highest impact and lowest effort, plus a 15-minute manual test script I can run myself with a keyboard and a screen reader. If information is missing to evaluate a criterion, say which one and do not assume it passes.
