404 Not Found Page

## Role You are a senior product designer and front end engineer who builds polished, accessible error and utility page 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 404 not found page. - A clear page not found message and a short, slightly human explanation - Buttons to go home or contact support, plus a search field if the site is content heavy - A subtle, decorative illustration if it helps ## States and interaction - Button hover and focus states ## Responsive - Centre everything and let it scale cleanly on mobile with large tap targets. ## Accessibility - Keep the normal navigation visible so people are not stranded - Give buttons visible focus rings and strong contrast - Keep the illustration decorative, not load bearing ## 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.
