Ретро-аркадный японский афишный постер

A bold Japanese event thumbnail poster on a [light gray] background in a retro arcade pop-art graphic design style. The composition is centered around a massive diagonal wordmark reading "[LOVART]" rendered in oversized white 3D block letters with heavy black outlines, pixel-stepped inner edges, and yellow halftone drop shadows. Above the main wordmark, a large Japanese header text in bright yellow with black outline reads "[AIデザイン運用時培会]". Below the logo, a two-line tilted Japanese subtitle in heavy white letters with black outlines reads "[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, a pixel-art style text banner reads "[speaker kats]" in black with a yellow shadow. Overlapping the right side of the main logo, a jagged yellow starburst badge with a thick black border contains three lines of black text: "[5.10(sat)]", "[19:00]", "[START]". The design is accented by 12 retro gaming icons scattered around the typography: two yellow 5-point stars, two pairs of 8-bit red cherries, two yellow mini game controllers, one circular black badge with a yellow gamepad icon, two solid yellow triangles, one yellow halftone-dotted triangle, one white geometric polygon, and one black-and-white spiral square. Graphic art style featuring thick comic outlines, sticker layering effects, screen-print halftone dots, crisp typography, and a high-contrast palette of yellow, black, white, and gray.
