+# OpenCloud 样式体系
+
+这套体系用于让视觉规则集中、Vue 模板可读，同时保留 Tailwind 对一次性布局的灵活性。它不是“所有样式都写成全局类”，而是把会跨页面复用、带有产品语义或必须一致的规则集中管理。
+
+## 分层
+
+| 层级 | 文件 | 职责 |
+| --- | --- | --- |
+| 设计令牌 | `src/styles/tokens.css` | 颜色、字体、渐变、阴影、动效时长等稳定决策 |
+| 基础规则 | `src/styles/base.css` | 页面基线、选中文本、全局圆角策略 |
+| 组件规则 | `src/styles/components.css` | 页面 Hero、容器、表单、面板、按钮等共享语义类 |
+| 第三方主题 | `src/lib/theme.ts` | Naive UI 的全局主题契约；值应与设计令牌保持一致 |
+| 单组件样式 | Vue 文件的 `<style scoped>` | 只属于一个功能的滑杆、动画、地图或媒体细节 |
+| 一次性布局 | Vue 模板中的 Tailwind 类 | flex/grid、间距、响应式排列及确实只出现一次的视觉调整 |
+
+`src/style.css` 只负责按以上顺序装配全局样式，不再直接堆放组件规则。
+
+## 命名规则
+
+- 所有共享类使用 `oc-` 前缀，避免与 Naive UI、AMap 和 Tailwind 冲突。
+- 组件使用 `.oc-block`，内部结构使用 `.oc-block__element`，变体使用 `.oc-block--modifier`。
+- 变体不能脱离基础类使用，例如 `oc-panel-button oc-panel-button--sky`。
+- 类名描述用途，不描述当前颜色。例如使用 `oc-field-error`，而不是 `oc-red-text`。
+- 只有至少跨两个页面复用，或承载全局产品规则时才新增共享类。仅服务单一功能的代码留在组件内。
+
+## 常用契约
+
+### 页面结构
+
+```html
+<section class="oc-page-hero">
+  <div class="oc-container oc-container--content oc-page-hero__inner">
+    <p class="oc-page-eyebrow">Cloud Upload</p>
+    <h1 class="oc-page-title">上传云图</h1>
+    <p class="oc-page-description">页面描述</p>
+  </div>
+</section>
+
+<main class="oc-container oc-container--content oc-page-content">
+  <!-- 页面内容 -->
+</main>
+```
+
+容器宽度只有三个语义档位：`oc-container--narrow`、`oc-container--content`、`oc-container--wide`。不要在同类页面重复手写 `max-w-* mx-auto px-*`。
+
+### 表单
+
+```html
+<label class="oc-field-label">
+  拍摄时间 <span class="oc-field-required">*</span>
+</label>
+<input class="oc-field-control" />
+<p class="oc-field-help">补充说明</p>
+<p class="oc-field-error">错误信息</p>
+```
+
+原生 `input`、`select` 和 `textarea` 共用 `oc-field-control`。尺寸或布局差异可以追加少量 Tailwind 类，例如 `class="oc-field-control mt-2 resize-none"`。
+
+### 信息与面板
+
+- `oc-section-label`：详情面板中的字段标题。
+- `oc-stat-label` / `oc-stat-value`：统计数据的标签和值。
+- `oc-inset-panel`：详情中的浅色信息块。
+- `oc-panel-card` / `oc-panel-card-soft`：Naive UI 卡片的硬阴影。
+- `oc-surface`：普通 HTML 容器的标准白色表面。
+- `oc-empty-card`：空状态表面。
+
+### 按钮
+
+Naive UI 按钮继续使用 `type="default"`，视觉语义由共享类控制：
+
+```html
+<NButton class="oc-panel-button oc-panel-button--neutral" type="default">
+  取消
+</NButton>
+<NButton class="oc-panel-button oc-panel-button--sky" type="default">
+  保存
+</NButton>
+```
+
+页面级主操作使用 `oc-primary-button`；面板内操作使用 `oc-panel-button`。可用变体为 `neutral`、`sky`、`teal`、`amber`、`danger`，不要临时创建新的强调色。
+
+## 新增或修改样式的决策顺序
+
+1. 先确认现有 `oc-*` 类能否表达该语义。
+2. 一次性布局使用 Tailwind，不为单次 `flex`、`gap` 或响应式网格创建共享类。
+3. 跨页面重复或属于产品视觉契约时，在 `components.css` 增加语义类；涉及稳定视觉值时先在 `tokens.css` 增加令牌。
+4. 只属于一个交互或组件的规则放在对应 Vue 文件的 `<style scoped>` 中。
+5. 修改 Naive UI 全局值时同步检查 `theme.ts` 与 `tokens.css`。
+
+## 验证
+
+提交前运行：
+
+```bash
+npm run check:styles
+npm run build
+```
+
+`check:styles` 会阻止已经淘汰的重复 class、非项目调色板以及缺少基础类的按钮修饰类回流；`build` 同时执行 Vue/TypeScript 类型检查和生产构建。
