Japanese Summer Accessory Ad Poster

Create a polished Japanese summer fashion advertisement poster in a square 1:1 layout, bright airy coastal lifestyle photography with a luxury catalog feel. Show a young woman from the waist up standing on a tropical beach with turquoise ocean, pale sand, soft sky, and slightly blurred palm leaves in the upper right background. She wears a wide-brim natural straw sun hat with a blue ribbon band, long straight dark hair, and a loose blue-and-white tie-dye top. Her face is obscured by a centered soft rectangular blur block. One hand lightly touches the brim of the hat. Add beachy hair accessories hanging from both sides of the hat and hair: strings with shells, beads, tassels, and round ornaments, including one long white-and-blue braided strand on the right side. She wears 4 visible jewelry items: a silver heart pendant necklace, a stack of beaded and metallic bracelets on one wrist, 1 shell drop earring on the left side, and 1 shell drop earring on the right side. Use soft natural sunlight, clean high-end product-ad styling, gentle skin tones, and refreshing summer blue color grading.

Design the image as a commercial poster with Japanese text and product callouts integrated around the model. In the upper left, place the handwritten English phrase {argument name="tagline" default="Summer Breeze"} in thin elegant white script. Below it, add a large Japanese headline in dark blue Mincho-style serif: {argument name="headline text" default="夏をまとう、私らしい輝き。"}. Under that, add two lines of smaller Japanese body copy in dark gray: "海風に揺れるアクセサリーで、" and "いつものコーデを特別に。".

On the left-middle, create a semi-transparent white rounded panel titled "— おすすめアイテム —" containing exactly 3 product cards arranged horizontally. Card 1 shows a silver heart necklace and the label "Ocean Heart Necklace" with price "¥2,980". Card 2 shows shell drop earrings and the label "Shell Drop Pierce" with price "¥2,480". Card 3 shows a natural bead bracelet and the label "Natural Beads Bracelet" with price "¥1,980".

In the lower left, add a blue circular discount badge with white Japanese text "期間限定" and large text "10% OFF". Overlapping it, place a white coupon pill with a small blue ribbon tab containing "クーポンコード" and the large code {argument name="coupon code" default="SUMMER10"}, plus small text "有効期限：2024.8.31まで".

At the top right, place a translucent aqua-blue circle badge with elegant light text reading "New Collection 2024". In the bottom left, add the brand logo text {argument name="brand name" default="LUMIERE"} in large serif capitals with smaller spaced text "ACCESSORY" beneath it. In the bottom right, place a large white rounded call-to-action button with a teal outline shopping cart icon and Japanese text {argument name="button text" default="今すぐチェック"}, followed by a right-pointing chevron. Keep all typography refined and balanced, with a premium Japanese fashion e-commerce promotional layout.
