Accessibility Audit

Audit the following code or page for accessibility issues against WCAG 2.2. Cover all three conformance levels:

**Level A (must fix)**
- Missing alt text on images
- Form inputs without labels
- Missing skip navigation links
- Keyboard traps (elements you can tab into but not out of)
- Missing lang attribute on html element

**Level AA (should fix)**
- Colour contrast below 4.5:1 for normal text, 3:1 for large text
- Missing focus indicators on interactive elements
- Touch targets smaller than 24x24 CSS pixels
- Content that reflows poorly at 320px width
- Missing error identification on form validation

**Level AAA (nice to have)**
- Contrast below 7:1 for normal text
- Sign language alternatives for media
- Reading level above lower secondary education
- Timing adjustments for all time limits

**ARIA Review**
- Incorrect or missing ARIA roles, states, and properties
- ARIA attributes that conflict with native HTML semantics
- Missing aria-live regions for dynamic content
- Widgets missing required ARIA patterns (e.g. tabs, dialogs, menus)

**Keyboard Navigation**
- Tab order that doesn't match visual layout
- Custom components that aren't keyboard operable
- Missing keyboard shortcuts for common actions
- Focus management after modal open/close

For each issue found, state: the element or pattern, the WCAG criterion it violates, the severity level, and a concrete fix.
