5.6 Component design (buttons, inputs, cards, etc.)

I’m working on a project about [describe your domain/product/idea]. I want to design core UI components. Can you help me with: 1. Listing essential components (buttons, forms, cards, inputs, modals). 2. Suggesting variations/states (hover, active, disabled). 3. Highlighting accessibility guidelines for components. 4. Suggesting how to integrate them into a design system. Format output as a component checklist.
