潮间带观察手册

设计一套「潮间带观察手册」的封面与现场记录跨页，3:2 横向展示，面向第一次参加海岸观察的家庭。封面以潮位标尺穿过礁石剖面，内页左侧按“出发前、抵达后、返程前”划分安全检查，右侧设置潮位、风向、底质、观察时段和同行人五个可填写字段；下方配三幅贝壳、蟹穴与藻带的铅笔轮廓，并用细线连接对应图注。页面准确出现「先看潮，再靠近」「不采集，只记录」「同行人确认」。采用耐水铅笔线、苔绿专色与暖白棉纸，窄体数字用于时间和刻度，折线避开复选框。屏幕阅读版保持同一顺序转为单栏，正文对比度不低于 4.5:1。不要出现真实机构徽标、公章、二维码、物种认证结论或危险行为示范；样例姓名与数据均为虚构。 记录示例写入“14:20、东北风、砂砾底质”，旁边画出由干纸色过渡到湿润深色的潮痕。封底用三枚小图说明结伴、保留退路和不翻石块。

Design the cover and a field-recording spread for “Intertidal Observation Handbook,” shown horizontally at 3:2 and intended for families joining a shore survey for the first time. On the cover, let a tide ruler pass through a cutaway of coastal rock. Divide the left page of the spread into three practical moments: before departure, after arrival, and before returning. On the right, provide writable fields for tide level, wind direction, substrate, observation window, and companion. Add three small waterproof-pencil studies of a shell, a crab burrow, and an algae band, each joined to its caption by a short leader line. Typeset the Chinese phrases 「先看潮，再靠近」「不采集，只记录」「同行人确认」 exactly. Use moss-green spot color, charcoal drawing, warm cotton paper, and narrow tabular numerals for time and tide marks. Keep the fold away from checkboxes and measured values. The screen-reading adaptation should preserve the same sequence in a single column with body-text contrast of at least 4.5:1. Do not show a real organization mark, official seal, QR code, species-certification claim, or unsafe behavior. All names and sample readings are fictional. Add one sample row using 14:20, northeast wind, and gravel substrate. Beside it, draw a tide stain shifting from dry paper color to a darker wet edge. Three back-cover vignettes show staying with a companion, preserving the return route, and leaving stones unturned. 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.
