Trois pages d'accueil mobiles de beauté

A polished promotional mockup showing 3 tall smartphone screens displayed side by side in a vertical triptych layout, each presenting a modern beauty brand landing page for a lip product. The overall composition is editorial, minimal, and premium, designed like a social media showcase of mobile web designs. The left panel sits on a soft lavender-to-blush gradient background and shows a black-framed phone with a cream and blush beauty website for {argument name="brand name" default="Kosas"}. At the top of this panel, small elegant serif text reads {argument name="left headline" default="Fresh Pout."}. The phone screen features a cropped close-up beauty image at the top, a bold headline reading “Lips in their fullest expression.” with “fullest” in italic serif styling, a rounded dark call-to-action button, a strip of 3 lip close-up thumbnails, 3 labeled benefit tabs reading “Plumps,” “Tingles,” and “Shines,” and a row of 5 shade or effect icons underneath. The middle panel sits on a lavender-to-deep-violet gradient background and shows a second black-framed phone with a more typographic landing page. Above it, serif text reads {argument name="middle headline" default="Claude Code"}. The screen includes a cropped portrait image at top, a very large bold black stacked title reading “LIP PULSE.” with a pink italic script-style line “is here.” beneath it, a rounded dark button, a dark section with the phrase “Lips in their fullest expression.”, and a product grid near the bottom containing 6 shade cards arranged in 2 rows of 3. The right panel sits on a dark navy textured background and shows a third black-framed phone with a pink-forward e-commerce style page. Centered above it, monospaced white text reads {argument name="right headline" default="GPT Images 2.0"}. This screen prominently displays the product hero section with the brand name “Kosas,” a large title “The Lip Pulse,” a pink lip gloss tube angled to the right, small feature icons, a shade strip of 6 lip swatches near the middle, and a lower promotional block with additional pink product imagery. Keep the layout symmetrical with exactly 3 phones, one per panel, each fully visible and vertically oriented. Use high-end cosmetic campaign aesthetics, clean spacing, fashion-web typography mixing serif and bold sans serif, soft pink and cream UI palettes, subtle shadows, and a sleek product-design presentation suitable for showcasing AI-generated mobile website concepts.
