Ultra-premium corporate seminar poster background for an event about [CHỦ ĐỀ]. The upper two thirds are a deep emerald green field with an abstract structure of thin golden lines forming an open network of nodes, fading in density towards the centre so a headline will sit cleanly on top. A subtle diagonal light sweep crosses the green, and a very fine noise texture keeps the flat colour from looking digital. The bottom third transitions through a soft feathered edge into a darkened, heavily blurred photograph of an attentive seated audience in a conference hall, dark enough to carry white speaker names and a logo row. One thin gold rule separates the two zones. Lighting logic is consistent: the golden network reads as if lit from the upper left, the audience band lit warmly from a stage in front of them. Palette is emerald, deep charcoal and metallic gold only. Professional, trustworthy, print-ready, vertical 4:5, no lettering anywhere, no text, no watermark.
