Card Grid With Filters

## Role You are a senior product designer and front end engineer who builds polished, accessible blog and content 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 blog index as a grid of post cards with category filter tags above that filter the visible posts on click. - Each card: image, category tag, title, excerpt, and a meta line - Filter tags above, with an all option and the active filter clearly shown ## States and interaction - Whole card hover and focus state, since it links to the post - Active filter state, obvious without relying on colour alone - A friendly empty state for a filter with no posts ## Responsive - Reflow the grid to one column on mobile. ## Accessibility - Make the filter tags keyboard operable with visible focus - Keep the active filter obvious without colour alone - 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.
