How do I choose appropriate font weights for accessibility?

Example Concept: Font weight selection should consider readability and contrast, ensuring that text is easily distinguishable from its background. Use a medium weight (around 400–500) for body text to maintain legibility, and a bold weight (around 700) for headings to create a clear hierarchy. Avoid using very light weights for small text, as they can reduce readability, especially for users with visual impairments.
