“Biennial North”是使用 FontVibe AI 创作的极简文字效果。深灰色几何无衬线字，字距宽松，下方一道发丝细线，平涂哑光，置于几乎空白的米白底上。

Create a finished minimalist poster for the design expo. Portrait 2:3 composition on a clean soft-white ground, evenly lit with diffuse light and no visible texture. Place exactly one line of type, “Biennial North”, centered horizontally around the vertical midpoint. Set it in bold geometric sans-serif letterforms with Futura-like construction: circular rounds, uniform stroke weight, high x-height, crisp horizontal terminals, and precise geometric joins. Keep the title on one line, generously tracked, soft charcoal, matte and sharply legible. Beneath it, place one delicate muted warm-grey hairline, centered and shorter than the title. Leave abundant uninterrupted white space above and below; restrained modernist authority, quiet architectural emptiness. No other words, symbols, imagery, borders, or ornament.
