5.12 Accessibility adjustments (color, contrast, sizing)

I’m working on a project about [describe your domain/product/idea]. I want to make accessibility adjustments in my UI design. Can you help me with: 1. Suggesting accessibility checks (contrast, font sizes, alt text, keyboard navigation). 2. Recommending design practices for inclusivity. 3. Highlighting common accessibility mistakes. 4. Suggesting tools for accessibility testing. Format output as an accessibility checklist I can follow.
