这不是一张静态壁纸，而是一幅每天重新落笔的山水画。 This is not a static wallpaper; it is a landscape repainted every day. 每日一景。山形、峰位、峰高、皴笔与苔点全部以当天日期为种子生成。同一天打开永远一致，跨天自动换一幅新画。同一组设置，365 天不重样。 A new scene each day. Ridgelines, peaks, texture strokes and moss dots are all generated from the date as a seed. The same day always looks the same; when the day changes, a new painting appears. One set of settings yields 365 different landscapes. 日月有历。日出日落按你所在经纬度实时计算，太阳沿昼夜弧线移动，夜里换成月亮。月相按朔望月推算，从朔日几乎不可见，到望日整圆，连续变化。 Sun and moon on schedule. Sunrise and sunset are computed from your coordinates in real time. The sun travels along a day-and-night arc and gives way to the moon after dusk. Moon phases follow the synodic month, from nearly invisible at new moon to a full disc at full moon. 天空应时。白天、晨昏、夜晚三套配色按当地时刻自动切换。日出与日落前后各三十分钟，天空、山体与云会被染上霞色。朝霞和晚霞各有百分之十的概率，不是天天都有，这更接近真实。 Sky in season. Three palettes — day, twilight and night — switch automatically with local time. Within thirty minutes of sunrise or sunset, sky, mountains and clouds take on a warm tint. Dawn glow and dusk glow each have a ten percent chance per day; they do not appear daily, which is closer to reality. 云随风动。云的速度来自实时风速，每五公里每小时一档，最高每秒十五像素。云形每绕回画面左侧一次就重新生成，避免循环重复的塑料感。 Clouds driven by wind. Cloud speed follows live wind speed in five-kilometre-per-hour steps, up to fifteen pixels per second. Cloud shapes are regenerated each time the bank wraps around to the left edge, so no pattern repeats visibly. 雨雪雷成象。按天气代码切换：细雨是斜线，大雪是圆点并左右摆动，雷暴每七秒闪白一次。雨越大，雨丝越多越长。 Rain, snow and thunder rendered as weather. Rain becomes slanting strokes, snow becomes drifting dots, and thunderstorms flash the sky white every seven seconds. Heavier rain means more and longer strokes. 水纹映身。水面横线的条数代表当前压力，越紧张条数越多；波幅代表当前心率，越接近你设定的最高心率，波纹越皱。左右两道弧分别是身体电量与血氧。 Ripples reflect your body. The number of horizontal water lines reflects current stress — the more tension, the more lines. Their amplitude reflects heart rate — the closer to your configured maximum, the choppier the water. The two side arcs show Body Battery and pulse oximetry. 雁随人行。七只小雁的位置代表今天的进度，步数决定左右，爬楼决定高低。走得越多，雁越往右上飞。 Geese follow your movement. The position of seven small geese tracks today's progress: steps set the horizontal position, floors climbed set the height. The more you move, the higher and further right they fly. 未读可见。手机有未读通知时，左下角石头上出现一枚小信封，红点标注数量；没有未读就完全不出现。 Unread at a glance. When the phone has unread notifications, a small envelope appears on the stone in the lower-left corner with a red badge showing the count. With no unread items, nothing is drawn. 预警不打扰。当地有气象预警时，底部只显示预警原文；没有预警时，才轮播你自己写的五句短语。 Alerts without clutter. When a local weather alert is active, the bottom line shows only the official alert text. When there is none, it cycles through five phrases you write yourself. 【画面怎么读 / How to Read the Face】 橙金色圆盘是太阳，三层同心圆做光晕。它的颜色随紫外线指数变化：UV 三级及以下偏橙，四到六级转琥珀，七级以上接近白色。 The orange-gold disc is the sun, drawn with three concentric halos. Its colour follows the UV index: orange at UV three and below, amber at four to six, near white at seven and above. 米白色、带缺角的圆是月亮。它由一行行被照亮的横段拼成，界线是椭圆投影，所以朔日几乎看不见，上下弦是直边半圆，望日才是整圆。 The cream-white circle with a missing edge is the moon. It is built row by row from illuminated segments bounded by an elliptical terminator, so it is almost invisible at new moon, a straight-edged half at the quarters, and a full disc at full moon. 夜间的白色小点是星星，共二十四颗，约四成会呼吸：亮度按四秒周期起伏，分成两组反相，因此此消彼长，而不是齐闪。 The white dots at night are stars: twenty-four of them, about forty percent of which breathe. Their brightness oscillates on a four-second cycle in two counter-phase groups, so they fade in and out alternately rather than blinking together. 云量低于四成画一层，四到七成画两层，超过七成画三层，雷暴固定三层。云速就是风速：五公里每小时以内每秒一像素，五到十是两像素，十到十五是三像素，以此类推，最快每秒十五像素。有阵风时，云在平均风与阵风之间来回摆，形成时快时慢。 Cloud cover below forty percent draws one layer, forty to seventy-five draws two, above seventy-five draws three, and thunderstorms always draw three. Cloud speed equals wind speed: one pixel per sec

1.1.3 月亮月相修复、月亮应用真实纹理，表达压力与心率的水纹不再稀疏，顶部日期往下移动一点，底部文字显示修复；云和船的速度线性增加，云关联风速，船速关联步频，太阳颜色随UV变化 一、位置数据的精度 1. Accuracy of Location Data 发送到服务器的经纬度只保留小数点后两位（约 1.1 公里精度），不包含设备标识、账号或任何可识别个人身份的信息。 Coordinates sent to the server are rounded to two decimal places (approximately 1.1 km precision). No device identifiers, accounts, or personally identifiable information are included. 二、天气与预警的数据来源 2. Sources of Weather and Alert Data 天气与气象预警均来自第三方中继服务，表盘本身不直接连接气象机构。中继向 meteoblue 请求气象与预警数据。 Weather and alert data are provided through a third-party relay service; the watch face does not connect to meteorological agencies directly. The relay requests weather and alert data from meteoblue. 区域差异：中国大陆境内，预警请求发送至中国气象局（NMC）的公开接口；中国大陆以外地区（包括美国、加拿大、中国香港、泰国等），预警请求发送至当地公开气象接口。 Regional routing: within mainland China, alert requests go to the public interface of the China Meteorological Administration (NMC); outside mainland China (including the United States, Canada, Hong Kong SAR of China, and Thailand), alert requests go to local public weather interfaces. 三、为什么采用中继架构 3. Why a Relay Architecture Is Used 手表表盘可用内存非常有限。若由表盘自行下载并解析原始气象与预警数据，会显著抬高内存峰值：轻则触发内存不足而崩溃，重则不得不放弃现有的大量绘制内容，也就不会有现在这样的山水画面。把解析交给中继，表盘只接收已经精简过的结果，才能在有限内存里同时保证稳定与画面表现。 Memory available to a watch face is very limited. If the watch face downloaded and parsed raw weather and alert data itself, peak memory usage would rise sharply — at best causing out-of-memory crashes, at worst forcing us to abandon most of the drawing, which would mean losing the landscape artwork you see now. By moving parsing to the relay, the watch face receives only condensed results, keeping both stability and visual richness within a small memory budget. 四、关于帆船变色 4. About the Sailboat Changing Color 帆船变色是一种预警提示。它依赖上述第三方数据，可能滞后或不准确。若你看到帆船变色，请以当地气象机构发布的官方信息为准，不要仅凭表盘做出安全判断。 A color change in the sailboat is an alert indicator. It relies on the third-party data described above and may be delayed or inaccurate. If the sailboat changes color, please refer to the official information published by your local meteorological authority, and do not make safety decisions based on the watch face alone. 五、可能的失效情形 5. Possible Failure Conditions 以下情况都可能导致预警缺失或不准：网络传输不稳定、中继服务临时不可用、公开气象接口调整或关闭、上游数据本身延迟。这些属于服务链路的客观风险，我们无法承诺预警的实时性与完整性。 Alerts may be missing or inaccurate under any of the following conditions: unstable network transmission, temporary unavailability of the relay service, changes to or closure of public weather interfaces, or delays in upstream data itself. These are inherent risks of the service chain; we cannot guarantee the timeliness or completeness of alerts. 六、免责声明 6. Disclaimer 本表盘提供的气象与预警信息仅供参考，不构成任何形式的安全建议。请勿将表盘作为灾害天气下出行、运动或避险的唯一依据。 Weather and alert information shown on this watch face is for reference only and does not constitute safety advice of any kind. Do not rely on the watch face as your sole source of information for travel, exercise, or evacuation during severe weather.
