a detailed Product UI Styleguide organized in a clean grid layout. It features sections for color tokens, typography scale, spacing, radius, elevation, buttons, inputs, chips, tabs, cards, and alerts. The color palette uses blues, whites, grays, and blacks with clear contrast. Typography is primarily sans-serif with a clear hierarchy from large bold headlines to smaller captions and button labels. Various UI elements are shown with normal, hover, and pressed states to demonstrate interactivity. The overall design intent is to offer a consistent, modular, and clear visual and interaction system for product UI development.
