Create ONE finished 1024x1024 Shopee cover for Royal Spa.

NEW-LANE TEMPLATE RULE:
- The first uploaded image is the local Royal Spa template preview for this exact SKU. Use it as the composition/background/template guide: sage-green shop background, title area, hook area, 3 USP cards, hero product zone, warranty footer, and clear bottom-left Shopee safe zone.
- Improve it into a polished real AI cover, but keep the same shop layout. Do not create a new design direction.
- Do not use CSSD74/design_ref as product reference. The uploaded preview is only the current template/layout guide for this SKU.

PRODUCT PHOTO FIDELITY:
- Product/source photos uploaded after the preview are the truth for product shape, color, usage position, part count, camera/head/nozzle/controller/strap details, and any visible maker marks.
- Product photos outrank all text.
- Do not add boxes, bottles, cables, tanks, extra heads, extra units, accessories, cameras, or parts unless visible in source photos.
- If product is wearable/on-face, prefer a real on-human usage hero when the uploaded refs include one.
- If product has camera/head/lens/nozzle, preserve the exact visible head/lens/nozzle shape.

PRODUCT IDENTITY REVIEW:
- Visual class: camera_visual_device
- Hero rule: Prefer a clean full product image of the blue dental scaler; current refs are mostly dark infographics and 3D tooth diagrams.
- USP visual rule: USP crops can show LED/blue light, phone camera view, and scaler tip, but need product-visible crops.
Must preserve:
- dark-blue pen body
- thin metal scaler tip
- blue LED/camera visual at tip
- vertical handheld scaler form
Forbidden:
- do not turn into white CSSD248 scaler, toothbrush, water flosser, or ear cleaner
- do not use tooth diagram as the product hero

TEXT LOCK:
- Render Vietnamese text exactly as below.
- Product title must be uppercase.
- Keep title readable, max 2-3 lines, and do NOT overlap product.
- USP headings must be bold and visually stronger than body.
- USP body must stay short and readable.
- Do not add extra USP cards or extra claims.
