復古遊戲風格日式活動橫幅

Create a bold Japanese event thumbnail in a retro 8-bit video game style on a clean white background with a black, white, and vivid yellow color palette. The composition is a single highly graphic poster packed with pixel-art decorations, thick black outlines, comic halftone dots, drop shadows, and arcade-inspired stickers. In the center, place an enormous headline reading “{argument name="main title" default="LOVART"}” in oversized block letters, bright yellow with a thick black outline, white border, and heavy shadow, slightly tilted and dominating most of the image. Above it, add a jagged white banner with black outline containing the Japanese title “{argument name="top banner text" default="AIデザイン運用勉強会"}”. Below the main title, place a black ribbon with yellow and white Japanese text reading “{argument name="subheading text" default="最新ツール実践 × プロの基礎力"}”. At the lower left-center, add a large rounded rectangular date panel in yellow with black outline and white trim, including a pixel calendar icon on the left and the text “{argument name="event date" default="5.10 (sat) 19:00 START"}” in huge black retro type. At the lower right, place a black spiky label reading “speaker” above the large yellow-outlined name “{argument name="speaker name" default="kats"}”. Surround the layout with exactly 11 decorative gaming elements: 1 pixel speech burst at upper left saying “LEVEL UP!”, 1 yellow lightning bolt near the top, 1 yellow question block with a black question mark at upper right, 1 pixel sword on the right side, 1 starburst on the right saying “GAME ON!”, 1 chibi pixel character jumping on the left in a yellow jacket with raised fist, 1 small black “1UP” life icon with three yellow hearts at lower left, 1 retro game controller beneath it, 3 groups of sparkle stars scattered around the composition. Add comic accents such as dotted halftone patches, angled yellow speed lines, small checkerboard strips, and a pixel cursor pointer near the subtitle. Include a stylized anime-like speaker avatar in the lower right corner wearing a black cap and black hoodie with yellow accents, Show every face clearly with natural, detailed facial features, integrated like a streamer or event host badge. Make all Japanese and English text crisp, readable, and accurately typeset, with the overall feeling of a high-energy YouTube thumbnail or social media event banner for a design/AI workshop.
