Create a commercially usable 9:16 vertical advertising gallery case image for a beverage campaign. Scene: a realistic metro-station lightbox mockup viewed straight-on with a slight environmental perspective, installed in a brushed metal frame on a clean tiled wall, glossy protective glass, soft reflections from the station floor, and believable transit signage blur in the far background. The lightbox should feel premium, bright, and production-ready, as if photographed in a real underground passage. Poster composition inside the lightbox: build a debranded tea launch poster with a strong central hierarchy. Place the main headline in the upper-middle area and use the exact copy "New Chinese Tea Launch" as the dominant title. Add a smaller secondary label above or below it, plus a restrained information block for campaign details using placeholder text only, with no real prices, addresses, phone numbers, QR codes, social handles, or brand claims. Reserve the lower-right or lower-center area for a product hero: a tall transparent cup of iced tea with visible citrus slices, tea leaves, ice cubes, and condensation, standing on a textured stone pedestal. Surround it with a few botanical accents and fruit segments near the base. Keep typography unobstructed and readable from distance. Art direction: use an elegant East-Asian-inspired botanical atmosphere without imitating any existing brand identity. Background artwork should combine soft misty mountain silhouettes, subtle sun-disc shape, layered paper-like textures, and clean negative space. Color palette: deep forest green, warm ivory, muted gold, tea amber, and small accents of pinkish citrus flesh. Materials should feel tactile and premium: matte printed poster paper, luminous backlit panel, brushed stainless frame, polished glass, damp fruit surface, and cold drink condensation. Lighting: internal lightbox illumination should be even and bright, with a warm-neutral white balance. Add realistic overhead station lighting, gentle floor bounce, faint glass glare, and mild shadow separation around the frame. Avoid harsh contrast; preserve legibility across all text zones. Typography rules: use a refined serif or high-contrast display face for the main title and a clean sans-serif for supporting information. Keep text blocks aligned and spacious, with clear zones for headline, subtitle, feature list, and callout panel. All text other than "New Chinese Tea Launch" should be generic placeholder copy or simple abstract marks. Do not include logos, trademarks, creator credits, pricing, or recognizable proprietary wording. Reference-image policy: use the provided reference only as inspiration for layout hierarchy, premium beverage poster logic, backlit transit placement, material finish, and scene realism. Do not reproduce any exact brand names, logos, protected wording, specific price formatting, QR design, or distinctive graphic elements from the source. The final image must look like a new original campaign mockup for a different customer. Negative constraints: no copied branding, no exact upstream text, no faces as primary subject, no messy clutter, no warped poster edges, no unreadable tiny text, no fantasy architecture, no extra products blocking the headline, no watermarks, no fake certification badges, no invented promotional dates or contact details.
