Event Poster with Retro Arcade LOVART Logo

A bold Japanese event thumbnail poster on a light gray background, designed in a retro arcade pop art style. At the center of the composition is a huge diagonal wordmark reading “LOVART”, set in oversized white block lettering with a thick black outline, a chunky 3D feel, subtly pixel-stepped inner edges, and yellow halftone shadow accents. Above the wordmark, place a large bright yellow Japanese headline with a black outline: “AIデザイン運用時培会”. Below the main wordmark, add two slightly slanted lines of bold white Japanese subtitle text with black outlines: the first line reads “最新ツール実銃 ×”, and the second line reads “プロの暗続力”. At the lower center, place a pixel-style black text label with a yellow drop shadow reading “speaker kats”. On the right side, overlapping the main logo, add a bright yellow jagged starburst badge with a thick black outline, containing three stacked lines of black text: “5.10(sat)”, “19:00”, “START”. Around the logo, scatter 12 playful game-inspired decorative icons and shapes: 2 yellow five-point stars, 2 pairs of red cherries with green stems, 2 small yellow game controllers, 1 black circle containing a yellow controller symbol, 2 solid yellow triangles, 1 yellow dashed triangle, 1 white outlined polygon, and 1 small black-and-white spiral square. Use a high-contrast palette of yellow, black, white, and light gray, with bold outlines, sticker-like layering, comic halftone dots, and crisp, readable Japanese typography.
