Write an Accessibility Audit

Conduct an accessibility audit of the following interface:

Interface: [describe the website, app, or component to audit]
WCAG level to target: [AA / AAA]
Primary user concerns: [e.g. blind users / low vision / motor impairment / cognitive disabilities / elderly users]
Tech stack: [e.g. React / plain HTML / mobile native]

Audit against these WCAG 2.1 success criteria — for each, state Pass / Fail / Needs Review and provide specific findings:

Perceivable:
- 1.1.1 Non-text content (alt text)
- 1.3.1 Info and relationships (semantic HTML)
- 1.4.3 Contrast (minimum 4.5:1 for text)
- 1.4.4 Resize text (up to 200% without loss of function)

Operable:
- 2.1.1 Keyboard accessible
- 2.4.3 Focus order (logical tab sequence)
- 2.4.7 Focus visible
- 2.5.3 Touch target size

Understandable:
- 3.1.1 Language of page
- 3.2.1 On focus (no unexpected context changes)
- 3.3.1 Error identification

Robust:
- 4.1.2 Name, role, value (ARIA usage)

Output: prioritised fix list with code examples for each failure.
