城市夜鸟观察报告

完成「城市夜鸟观察报告」的摘要封面与数据跨页，3:2 横向，呈现一项虚构的夜间公民观察。左页将 19:00 至 24:00 分为半小时格，用圆点表示听见、看见和不确定三类记录，旁边的方向玫瑰图显示声音来源；右页画出停栖、鸣叫、短距飞离三种行为线描，并设置光照级别、天气、观察分钟、距离和可信度字段。标题下准确出现「保持距离」「不用闪光灯」「不确定也可记录」。图注直接贴近数据，单位不得脱离数值。采用午夜蓝底、雾白文字和少量琥珀色标记，数字用等宽字，正文用清晰黑体。电子版提供表格替代文本和不依赖颜色的符号。禁止真实物种结论、精确巢址、研究机构标识、认证章、二维码或惊扰鸟类的画面。 矩阵下方放一条 60 分钟样例：前段无记录，中段两次不确定叫声，末段一次飞离。右下角提供“提前结束：强光／施工／身体不适”字段。

Complete the summary cover and data spread for “Urban Night Bird Observation Report,” a fictional citizen-science study shown horizontally at 3:2. Divide the left page from 19:00 to 24:00 in half-hour cells. Use distinct dot symbols for heard, seen, and uncertain records, and place a direction rose beside the matrix to show where calls originated. On the right, draw three restrained behavioral studies: perching, calling, and a short departure flight. Include labeled fields for light level, weather, observed minutes, distance, and confidence. Under the title, typeset the Chinese notices 「保持距离」「不用闪光灯」「不确定也可记录」 exactly. Keep captions beside the data they explain and never separate a unit from its value. Use a midnight-blue ground, fog-white text, and sparse amber marks. Set numerals in a monospaced face while continuous Chinese text uses a clear sans serif. The digital version needs text alternatives for the matrix and symbols that do not rely on color alone. Do not state real species findings, reveal a precise nest location, imitate a research institute, add a seal or QR code, or depict flash photography and other disturbance. Below the matrix, show a sixty-minute example with no record at first, two uncertain calls in the middle, and one departure at the end. A lower-right field allows early completion for bright light, construction noise, or physical discomfort. Final art direction: editorial document and publication design with precise hierarchy and print-aware spacing. Use this controlled palette as the dominant visual system: #F4F0E7, #28343B, #6F8176, #B96C4A; preserve believable local material colors within it. Preserve the requested text hierarchy and wording as part of the design, but do not invent extra slogans, pseudo-text, logos, or watermarks. Keep one unmistakable primary subject or information route and one readable visual action. Use disciplined negative space and avoid default perfect symmetry. Physical credibility is mandatory: correct gravity, contact shadows, material thickness, tool weight, joint loading, fabric tension, liquid direction, reflections, scale, and occlusion. Create an original visual with no resemblance to a public figure, copyrighted character, existing campaign, or living artist signature style. No unrelated decorative icons, floating objects, duplicated limbs, plastic gloss, waxy skin, synthetic collage artifacts, or AI watermarks. Return exactly one finished image composed for 3:2; no variants, process sheet, split panels, mockup frame, or contact sheet.
