Cartel de evento interdisciplinar en estilo geométrico luminoso

Organize any thematic content into a bright, clean event-poster visual, using large theme-derived bright-colored circles and cropped semicircular arcs as the graphic force seen first; let them flow in from the edges and overlap one another, forming a group of soft, transparent color-block pressures; keep the base layer neutral light gray or a low-saturation light ground derived from the theme, with the bright colors occupying the main area, dark cool colors carrying the title, emphasis marks and a few linear anchors, and white serving only as small dots, thin lines and local text highlights — overall high brightness, high contrast, clean and free of grime. Use for the title a heavy, high-contrast Chinese display type, dark, large-scale, tight line spacing, placed on a left-leaning visual center; the text block should feel pressed onto the bright circle's surface rather than floating in emptiness; for auxiliary information use a small, orderly type, arranged in vertical groups on the left and a narrow column on the right, keeping clear bullet points, thin horizontal rules, short color bars and a date-number hierarchy, so the reading path enters through the big title, passes to the speakers or core info, then falls to the details at the bottom and sides. Add to the background a semi-transparent grid, faint large English or theme-word shadows, thin straight lines, dots, small concentric circles and moon-phase-like repeated semicircles; all decoration must obey the order of information: some hug the title forming rhythm, some extend along the edges, some are covered by the large circles, revealing only parts. When colors vary by theme keep the role relationships: the largest area is a bright, clean warm main color, the neutral light ground holds the layout, dark cool colors provide the text skeleton and a few dots, and a few light-gradient circles create spatial layers; edges are mainly smooth and hard like digital vector printing, with slight softening at transparent overlaps, adding no paper aging, heavy shadows or realistic materials. The image should have the rational density and crisp order of an academic event, avoiding turning the geometric elements into evenly scattered decoration and avoiding letting the small text steal the weight of the main title. —————— Theme: an event poster for a young scholars' interdisciplinary sharing session, conveying an open and professional atmosphere of exchange Note: keep a small amount of speaker and event-time information Format: vertical 9:16
