Create a high-impact visual for a fictional Japanese advertisement theme, aimed at going viral on social media. On a 1:1 square canvas, arrange 4 types of ads in a 2x2 grid. Genres: ① Tech (AI/App), ② Beauty/Cosmetics, ③ Food & Drink, ④ Fitness. All with Japanese copy and fictional brands. Requirements for virality: eye-catching catchphrases, emotional triggers (surprise, empathy, urgency, desire), high-contrast colors (neon, vivid, black×fluorescent), bold layouts (overflow, diagonal, oversized text), thumbnail-friendly composition (center focus, face close-up, gaze direction), and SNS ad-style elements (arrows, emphasis frames, speech bubbles). Design style: 2025 trend SNS ad style, TikTok/Instagram ad style, readability prioritized (viewable on mobile), photo-like or high-quality illustration, with CTA (e.g., free now, limited, 3 days left). Random viral elements: choose one each from ① forbidden words (e.g., 'Don't know and you'll lose'), ② gap appeal (e.g., 'Looks cute but inside is crazy'), ③ numbers/limited (e.g., '3-day limited'). Ensure each of the 4 ads has a distinct atmosphere, grid intact, text readable, and intentionally include 'scroll-stopping discomfort'.
