Event Poster Retro 8-Bit Japanese Arcade

On a clean white background, create a bold Japanese event thumbnail in a retro 8-bit video game style using a black, white, and bright yellow color scheme. The composition is a highly graphic poster filled with pixel art embellishments, thick black outlines, manga halftone dots, drop shadows, and arcade-style stickers. In the center, place a huge title, "{argument name="main title" default="LOVART"}", in an oversized blocky typeface, bright yellow with a thick black outline, white border, and heavy shadow, slightly tilted and taking up most of the image. Above the title, add a jagged white banner with a black outline containing the Japanese headline "{argument name="top banner text" default="AI设计运营研讨会"}". Below the main title, place a black ribbon with yellow-and-white Japanese text reading "{argument name="subheading text" default="最新工具实践 × 专业基础能力"}". In the lower-left center, add a large rounded-rectangle date panel filled with yellow, outlined in black with white trim, including a pixel calendar icon on the left and displaying "{argument name="event date" default="5.10 (周六) 19:00 开始"}" in huge black retro lettering. In the lower right, place a black spiky label reading "speaker" above the large text "{argument name="speaker name" default="kats"}" with a yellow outline. Around the layout, add 11 decorative game elements: a pixel speech bubble in the upper left reading "LEVEL UP!", a yellow lightning bolt near the top, a yellow question block with a black question mark in the upper right corner, a pixel sword on the right, a starburst graphic on the right reading "GAME ON!", a chibi pixel character on the left wearing a yellow jacket and jumping with a raised fist, a small black "1UP" life icon with three yellow hearts in the lower left, a retro game controller beneath it, and 3 groups of sparkling stars scattered throughout the composition. Add comic-style decorations such as dotted halftone patches, slanted yellow speed lines, small checkerboard stripes, and a pixel cursor pointer near the subtitle. In the lower-right corner, include a stylized anime avatar wearing a black hat and a black hoodie with yellow accents, with the face partially obscured or simplified, integrated like a streamer or event host badge. Ensure all Japanese and English text is clear, readable, and accurately typeset, with an overall high-energy YouTube thumbnail or design/AI seminar social media banner vibe.
