Sidebar + Main Content

## Role You are a senior product designer and front end engineer who builds polished, accessible dashboard UIs. ## Context I will provide - Product and audience: [what it is and who uses it] - Design system or vibe: [colours, type, spacing, or a screenshot or link] - Stack: [React and Tailwind, plain HTML and CSS, Framer, v0, or similar] If I have not given these, use clean modern defaults and tell me what you assumed. ## Build Build a dashboard with a vertical sidebar and a main content area. - A left sidebar with links that have icons, labels, and a clear active state - A main area with the page title, key actions, and content in a sensible hierarchy ## States and interaction - An empty state for no data yet and a loading state with skeletons ## Responsive - On mobile collapse the sidebar behind a menu button and let the content go full width. ## Accessibility - Give every link a visible focus ring and make it keyboard operable - Never rely on colour alone to show the current or active item - Keep contrast strong ## Output Production ready code in my stack, or a clear component spec if I have not named a stack. Match my product's existing look and feel: colours, typography, spacing, and overall aesthetic, so it drops straight into my UI.
