The prompt

Build a two-option purchase comparison with Tailwind CSS for a product sold either as a subscription or as a perpetual licence. Use a max-w-4xl section with a centred heading and a muted subline about choosing how to pay. Underneath, two equal cards in a grid. The left card is the subscription: a small label, price per year, a short paragraph, and a bulleted list where every line is a check. The right card is the perpetual licence, visually heavier with a neutral-900 border and a small dark "Own it" ribbon in the corner: a one-time price, a paragraph explaining updates are included for twelve months, and a mixed list where two lines carry a muted cross glyph to show what stops after a year. Under both cards, a full-width neutral-50 strip with three columns comparing cost after one, three and five years, with the cheaper figure in each column set in medium neutral-900 and the other muted.
