Generate a NEW original Vietnamese historical thumbnail image, inspired by the supplied reference only for overall poster mood, parchment/ink texture, and calligraphy-poster design language. Do NOT copy the reference composition, character pose, face, background, title layout, colors exactly, or any existing text placement. Create a distinctly different original poster for Trần Nguyên Hãn.

16:9 horizontal YouTube thumbnail, true poster composition. Subject: Trần Nguyên Hãn, heroic Vietnamese Lam Sơn general, early 15th-century Đại Việt, wearing culturally accurate Vietnamese Lam Sơn armor/robe, stern noble face, holding a command sword and standing near a river pier/war boats to hint at his military campaigns. Background: misty Đông Quan/Lam Sơn battlefield, bamboo silhouettes, Vietnamese banners, smoky bronze sky. Design: antique parchment and ink wash, sepia/bronze/gold palette, dramatic historical documentary poster, large dark ink-brush title panel placed on the LEFT side (not the same as reference), gold Vietnamese brush calligraphy title text: "TRẦN NGUYÊN HÃN". Add subtle red seal-like accent but no logo.

Reference usage: style reference only, not identity or layout. Make a new image from scratch, different from the reference; do not recreate Lê Lai or any unrelated warrior from the reference. Negative: no copied reference face, no copied reference pose, no identical title panel, no extra text, no watermark, no logo, no modern objects, no photorealism, no anime, no 3D, no European armor, no Chinese imperial robe, no crop/pad/resize from scene image.
