Monthly / Annual Toggle

## Role You are a senior product designer and front end engineer who builds polished, accessible pricing 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 pricing section with a monthly and annual billing toggle. - A toggle at the top with a save badge on the annual option, and prices that update on selection - Plan cards with names, prices, feature lists, and buttons ## States and interaction - The toggle shows its current state and updates prices smoothly - Hover and focus states on the cards and buttons - The toggle is keyboard operable with a visible focus state and an accessible label ## Responsive - On mobile keep the toggle prominent above the stacked cards. ## Accessibility - Keep contrast strong - Keep the current billing choice obvious - Give the toggle an accessible label ## 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.
