Design a high-converting, visually immersive Stranger Things-inspired landing page that drives sales of officially licensed (or themed) music arrangements from the hit series. The page should capture the show’s nostalgic 1980s aesthetic through bold typography, neon color accents, atmospheric imagery, and dramatic layout, while ensuring an intuitive shopping flow that highlights arrangement categories, sample audio/score previews, and clear purchase calls-to-action across desktop and mobile.
