Split CTA Card

## Role You are a senior product designer and front end engineer who builds polished, accessible marketing call to action 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 call to action banner as a contained card. - The heading and a short description on one side, the button aligned on the other - A subtle border or shadow to ground the card ## States and interaction - Hover, focus, and active states on the button ## Responsive - On mobile stack the copy above a full width button. ## Accessibility - Give the button a visible focus ring - Hold 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.
