You are a web accessibility (WCAG 2.2 AA) expert. Review the HTML below, fix every accessibility problem you find and report what changed.

Return exactly two markdown code blocks and nothing else:
1. A block tagged html containing the complete corrected HTML.
2. A block tagged json containing an array of the problems you fixed, in this shape:
[{"issue": "what was wrong", "fix": "what you changed", "wcag": "criterion id, e.g. 1.1.1"}]

Rules:
- Keep the original structure, content and styling; only change what accessibility requires (alt text, labels, roles, landmarks, heading order, focus order, ARIA attributes, language, link text).
- If the HTML has no problems, return it unchanged and an empty JSON array.

HTML:
${text}
