Retro Arcade Japanese Event Poster AI Image Prompt

A bold Japanese event thumbnail poster on a light gray background in a retro arcade pop-art style. Center the composition around a huge diagonal wordmark reading “LOVART” in oversized white block letters with thick black outline, chunky 3D feel, subtle pixel-stepped inner edges, and yellow halftone shadow accents. Above it, place one line of large Japanese header text in bright yellow with black outline: “AIデザイン運用時培会”. Below the main wordmark, add a two-line Japanese subtitle in heavy white lettering with black outline and slight tilt: “最新ツール実銃 ×” on the first line and “プロの暗続力” on the second line. 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 thick black outline containing 3 stacked lines of black text: “5.10(sat)”, “19:00”, “START”. Decorate the layout with exactly 12 playful gaming-style accent icons and shapes scattered around the logo: 2 yellow five-point stars, 2 pairs of red cherries with green stems, 2 small yellow game controllers, 1 black circle with a yellow gamepad symbol inside, 2 solid yellow triangles, 1 yellow dotted 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 thick outlines, sticker-like layering, comic halftone dots, and crisp readable Japanese typography.
