**Designer-grade vertical mobile wallpaper poster, 9:16 aspect ratio. Asymmetric composition with intentional imbalance and editorial rhythm. Luxury fashion magazine aesthetics.** **【Visual Style】** Cream white base with deep brown and warm orange as primary and secondary accent tones. Cold, editorial aesthetic with aggressive negative space, modular grid system, layered visual rhythm, cinematic cropping and element overflow, strong typographic contrast, luxury brand-level finish. **【Content — Academic Integrity Theme】** Left side: A geometric open book, aggressively cropped beyond the frame edge, in warm orange and deep brown tones, emanating a soft warm glow. Right side: Cinematic close-up of a hand gripping a fountain pen, tip lightly touching a geometric grid. Bright starburst light radiates from the pen tip, symbolizing integrity as a guiding light. Hand and pen partially overflow the frame, creating visual tension. Top: Vertically rotated headline "ACADEMIC INTEGRITY", ultra-thin elegant serif typeface, deep brown, placed at the extreme frame edge for visual tension. Bottom: Ultra-small metadata typography "青春筑诚信 · 笃行向未来", deep brown, generously spaced. Warm orange thin horizontal line as graphic anchor. Corner details: Minimalist geometric clock element partially visible in top right; three four-pointed stars scattered asymmetrically, warm orange, symbolizing the light of honesty. Overall feeling: Premium, editorial, cinematic. Not a typical campus poster — feels like a luxury brand campaign for integrity. Clean, bold, sophisticated.
