Futuristic Neon Themed Cart Page for Lead Generation Plans

Design a cart page that allows users to purchase one of the lead generation pricing plans (Starter, Growth, or Enterprise). The design should maintain the futuristic aesthetic, dark background, and glowing neon accents similar to the pricing plan UI.Plan Selection in Cart: Display the chosen plan(s) in an elegant card layout with glowing borders: Starter Plan, Growth Plan, or Enterprise Plan cards. Each plan card should include: Plan title (e.g., Growth Plan) Price (e.g., $49/month) Features in bullet points (e.g., AI powered lead generation, CRM tools, etc.) An option to modify the plan (for switching plans) or remove the plan with small glowing icons next to the plan card. Billing Summary: Below the plan selection, provide a summary section showing: Subtotal, Taxes, and Total Amount. A promo code entry box with a glowing border and "Apply" button. A small note for monthly billing cycles and the ability to toggle between monthly or yearly payments for discounts. Checkout Button: A large, visually striking “Proceed to Checkout” button at the bottom, using a neon gradient effect (e.g., purple transitioning to blue or green). Below the checkout button, display secure payment icons with a glowing outline (credit cards, PayPal, etc.). Add small text below the button, “You will be charged monthly/yearly based on your chosen plan.” Lead Management Integration: Add an option for add ons (e.g., additional leads or CRM tools), which can be selected via checkboxes or toggle buttons near the plan card. Include a small tooltip icon n
