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. Show every face clearly with natural, detailed facial features. 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.
