YouTube Thumbnail - Flashy Japanese AI Thumbnail

Create a hyper-saturated Japanese YouTube thumbnail in a flashy clickbait anime style, 16:9 landscape, with a split composition: huge stacked text blocks dominating the left two-thirds and an anime character on the right one-third. The background is a fiery explosion of red, orange, and gold energy with glowing sparks, lens flares, glittering star highlights, and a high-contrast metallic shine effect everywhere. On the left, place 4 bold text groups stacked vertically with thick black outlines, white inner strokes, intense outer glow, and glossy 3D treatment. Top line: giant Japanese headline text {argument name="headline text" default="紅エンジニア必見"} in vivid red with white edging and bright gold spark accents. Second line: a rounded square orange app-like icon with a white stylized "M" to the left of the word {argument name="product name" default="masatra"} in enormous lowercase white sans-serif letters with black outline and subtle gray shading. Third line: a black rectangular banner with compact bold white Japanese text reading "次世代AIエージェントフレームワーク". Bottom line: very large gold metallic Japanese text {argument name="bottom text" default="徹底解説"} with beveled 3D embossing, orange-to-gold gradient, bright specular highlights, and glowing edges. On the right, show 1 anime-style young adult woman from chest up, with {argument name="hair color" default="brown"} medium-length hair, wearing a white open lab coat over a white shirt, leaning toward the camera and pointing directly at the viewer with a foreshortened hand and extended index finger in the foreground. Her pose should feel confident, urgent, and attention-grabbing. Use dramatic rim lighting from the fiery background, strong orange highlights on skin and clothing, and a polished commercial thumbnail finish. Reserve a large rectangular area over the upper-right face region as a flat placeholder block in {argument name="placeholder color" default="light brown"}, obscuring most of the face. Make the overall design extremely dense, glossy, explosive, and optimized for maximum readability at small size.
