Generate a detailed feature page for the lightweight baby stroller based on the provided white-background product image; The stroller is made the sole subject, retaining its "MOCKUP" and "EMBRACE YOUR BEAUTY, UNLEASH YOUR POWER" logo, without adding any new brands, models, or text. The background is warm white, with the top aligned on the left with a heavy black title "Lightweight Travel Fully Upgraded," and a small lime dot and a short phrase "Comfortable New Experience" placed at the top right. Below is a four-card asymmetrical grid: the upper large truck displays the cart's sunshade partially with an upward curved arrow; Left medium truck shows seat support structure; Middle right: vertical large truck displays storage basket under the cart; The lower left card shows the widened wheelset. Each card features a light gray-white rounded background, with black subheadings and a short description, and lime green highlighted on the edges and key components. The title uses bold black sans-serif font, with medium weight sans-serif text on the card, and the main product or parts are clear and complete inside the card. Do not include baby images, real brands, patent numbers, exaggerated load-bearing or safety promises, screenshot edges, watermarks, garbled text, low-definition icons, or obvious shadows.
