极简黑白光影核心文案海报

设计一张抓人且直击人心的极简社论海报，精确围绕标题“{headline_text_zh}”（默认值：“太阳就站在黑夜的门口”）。使用超大、清晰易读的现代无衬线字体呈现标题，并将其作为画面中唯一可见文案；不要添加任何其他文字、副标题、标志或水印。不要对标题进行直白插图式解释，而是用克制的黑白光影表达：深黑到炭灰的背景中，在黑夜边缘或光影门槛处出现一个受控的温暖太阳般光晕，或使用同等简洁的希望隐喻。保持平静而有呼吸感的排版，强调明确层级、充足留白、精准对齐、平衡的不对称和高级社论克制。高对比度，只保留细微纸张或哑光颗粒，边缘干净如矢量图形，不要装饰杂乱，不要可识别品牌或命名设计师风格，不要求人物。竖幅 4:5 海报构图。

【English Prompt】
Design a striking minimalist editorial poster centered on the exact headline "{headline_text}" (default: "The sun stands at the door of night"). Show the headline in extra-large, highly legible modern sans-serif type as the only visible copy; do not add any other text, subtitle, logo or watermark. Interpret the headline intelligently rather than illustrating it literally: use a restrained monochrome black-to-charcoal field with a single controlled warm sun-like glow at a threshold of darkness, or an equivalent light-and-shadow metaphor that captures hope at the edge of night. Use a calm breathable layout with strong hierarchy, generous negative space, precise alignment, balanced asymmetry and premium editorial restraint. High contrast, subtle paper or matte grain only, clean vector-like edges, no decorative clutter, no recognizable brand or named designer style, no people required. Vertical 4:5 poster composition.
