Accessibility and Search Best Practices:
- Maintain alt attributes under 125 characters to prevent truncation by common screen readers (such as JAWS and NVDA).
- Never begin alt descriptions with "image of", "picture of", or "graphic showing" because assistive technologies announce image tags automatically.
- If an image is purely ornamental and contains no contextual or functional information, present an empty string:
alt="".
