Haz tuyo «Cartel de verano con flotadores amarillos y olas de acuarela»

Generate a high-end summer event graphic poster in vertical 3:4 format; it must be a finished poster with the typography already laid out. The main subject is a white poster sheet, with three yellow inflatable swim rings floating and spinning in the center amid blue watercolor waves. The swim rings are smooth, semi-transparent yellow rubber with soft highlights and slight translucency — not donuts, not food. The blue waves resemble transparent watercolor, seawater brushstrokes, summery trails, forming a flow line from upper right to lower left, mixed with light cyan-blue, mint blue, soft yellow halos, and a few star sparkles. At the edges of the background, a beach and horizon are faintly visible, but the main subject remains a clean white-ground design poster. The layout must be complete: at the upper left, a large Chinese main title «趁热去夏天» in heavy hand-drawn block lettering, cyan-blue body with yellow shadow, lively but not childish; small text to the upper right of the title reads «SUMMER DAYS.». Below the main title, a small Chinese caption: «这是属于夏天的长段落：把海风、阳光和冰凉的水声，写进一张明亮的海报里。». At the lower left, a yellow info block reading «去更远的地方，见更亮的光。»; the next line «Chase the Summer Light.»; then the subheading «夏日记»; below it three lines of small text: «醒来就闻到海盐和防晒霜的味道 / 不要回头 / 夏天明亮、漫长、懒散又电气。». At the bottom, small text on the left «Summer 的普通日», and small text at the lower right «像一颗气泡，漂进蓝色浪里». Overall style: summer event poster, Japanese magazine layout, watercolor waves, yellow swim rings, blue-yellow color clash, fresh white-ground commercial visual, lightly grainy paper, transparent water feel, bright natural light. Medium information density; the title, body text, info block, and small bottom text should form a complete advertising layout. Avoid: text-free background image, English dominance, donuts, food, people, swimsuit models, social app buttons, logo, watermark, garbled text, cheap e-commerce promotion, excessive cartoon style, dirty water surface, dark heavy shadows.
