Minimalist High-Key Morning Silhouette Poster

Vertical poster design featuring a central, backlit silhouette of [a person wearing a long coat] walking away mid-stride into a bright, hazy white void, with their edges softly diffused by intense high-key backlighting. Large, bold [orange] Chinese typography reads "[早安诸位]" horizontally across the center, partially over the figure. At the top edge, small [black] text reads "[MORNING NOTE • 2026-10-24 • TO EVERYONE]". At the bottom, a neat, centered block of small [dark brownish-orange] metadata text displays: "[主题 | 早安诸位]", "[日期 | 2026-10-24]", "[时刻 | 07:10 AM]", "[对象 | 晨间问候者，背身离场]", and "[备注 | 在近乎空无的白里，向更亮处迈一步，替今天先说一句早安。]". Minimalist, ethereal aesthetic with subtle film grain texture.
