+# HUD Panel Component Plan
+
+## Goal
+
+Unify Earth HUD panels into a reusable component layer so new panels can share:
+
+- a consistent shell
+- a consistent header
+- a consistent action-button system
+- a consistent body and collapse pattern
+
+## Scope
+
+Target panels:
+
+- `tv-panel`
+- `news-panel`
+- `legend`
+- `layer-panel`
+- `earth-stats`
+- `info-card`
+- settings modal header/actions
+
+## Component Model
+
+### Base shell
+
+- `.hud-panel`
+- `.hud-panel--compact`
+- `.hud-panel--media`
+- `.hud-panel--collapsed`
+- `.hud-panel-hidden`
+- `.hud-panel.is-dragging`
+- `.hud-panel.is-layout-animating`
+
+### Header
+
+- `.hud-panel__header`
+- `.hud-panel__title-group`
+- `.hud-panel__title`
+- `.hud-panel__subtitle`
+- `.hud-panel__chip`
+- `.hud-panel__actions`
+
+Header baseline rule:
+
+- Header title styling is fixed by the component layer and should not drift per panel
+- Title font size, font weight, letter spacing, line height, text color, and vertical alignment come from the shared header tokens and structure
+- Header divider, border treatment, inner spacing, and title-to-actions alignment are part of the same shared baseline
+- Panel-specific header differences should be limited to explicit variants such as `compact` or `media`, or token overrides with documented intent
+- “Looks close enough” local header overrides should be treated as temporary compatibility code and removed during migration
+
+### Actions
+
+- `.hud-panel__action`
+- `.hud-panel__action--icon`
+- `.hud-panel__action--collapse`
+- `.hud-panel__action--close`
+- `.hud-panel__action--refresh`
+- `.hud-panel__action--external`
+
+Action-button baseline rule:
+
+- Header action buttons must have one fixed default style baseline across all HUD panels
+- Default width behavior, padding, icon size, radius, alignment, hover, and active feedback all come from `.hud-panel__action`
+- Panel-specific differences must be expressed through explicit variants or token overrides, not ad-hoc local button rewrites
+- `close` buttons are part of the same default action system and must not silently fall back to a separate legacy box model
+
+### Body
+
+- `.hud-panel__body`
+- `.hud-panel__body--scroll`
+- `.hud-panel__body--collapsible`
+
+### Collapse behavior
+
+- `.hud-panel--collapsed`
+- `.hud-panel--expand-up`
+- `.hud-panel--expand-down`
+
+Adaptive collapse / expand rule:
+
+- HUD panels support two expansion directions:
+  - top-to-bottom expansion
+  - bottom-to-top expansion
+- Expansion direction should be decided at runtime from available viewport space rather than hardcoded per panel
+- Use:
+  - `d` = available distance from the header anchor to the viewport bottom edge
+  - `h` = expected expanded panel height
+  - buffer = `20px`
+- Collapsed-state direction rule:
+  - if `d > h + 20px`, the next action direction is `expand-up`
+  - if `d <= h + 20px`, the next action direction is `expand-down`
+- To avoid jitter around the threshold, the shared controller should keep a small hysteresis band:
+  - if the current direction is already `up`, keep it until `d <= h`
+  - if the current direction is already `down`, keep it until `d > h + 20px`
+- The opposite edge is still a safety guard:
+  - if the chosen side cannot fit at all, fall back to the other side if it can fit
+  - if neither side fully fits, choose the side with more space and let the body scroll
+- If neither direction fully fits, choose the direction with more available space and let the body scroll
+- Collapse icon direction must match the active expansion direction so the icon always describes the real open/close motion
+- The collapse icon describes the next action, not the current state
+- This mapping is fixed component behavior and must not drift per panel:
+  - collapsed + expand-down => `expand_more`
+  - expanded + expand-down => `expand_less`
+  - collapsed + expand-up => `expand_less`
+  - expanded + expand-up => `expand_more`
+- Panels must not combine icon-name swapping with extra CSS rotation for the same collapse control
+- Expansion direction and icon direction must come from one shared source of truth in the component controller
+- The direction decision should be recomputed when opening, resizing the viewport, or restoring a dragged panel near another edge
+
+## Tokens
+
+Promote panel differences into CSS variables instead of duplicating selectors:
+
+- `--hud-panel-padding`
+- `--hud-header-padding`
+- `--hud-header-gap`
+- `--hud-action-padding`
+- `--hud-action-gap`
+- `--hud-action-icon-size`
+- `--hud-body-gap`
+- `--hud-body-max-height`
+- `--hud-chip-radius`
+- `--hud-title-font-size`
+- `--hud-title-font-weight`
+- `--hud-title-letter-spacing`
+- `--hud-title-line-height`
+- `--hud-title-color`
+- `--hud-header-border-color`
+- `--hud-header-divider-opacity`
+- `--hud-expand-direction`
+
+## Migration Order
+
+1. Build the shared component layer in `frontend/public/earth/css/hud.css`
+2. Migrate `tv-panel` and `news-panel` first as the reference implementation
+3. Migrate `legend` and `layer-panel` into a compact variant
+4. Migrate `earth-stats` and `info-card`
+5. Align settings modal header/actions with the same action system
+6. Remove legacy one-off button selectors after verification
+
+## Guardrails
+
+- Do not change panel behavior and data flow during the first pass
+- Keep old class names temporarily as compatibility hooks
+- Prefer variable overrides over per-panel reimplementation
+- Treat header action-button default styling as fixed component API, not per-panel design space
+- Treat header title typography, border, and divider styling as fixed component API, not per-panel design space
+- Treat collapse direction as a component behavior contract, not a one-off panel trick
+- Treat collapse icon semantics as a component behavior contract, not a per-panel visual preference
+- Verify header alignment and drag/collapse behavior after each migration batch
+
+## First Implementation Batch
+
+Batch 1 should only do:
+
+- shared header structure
+- shared action-button system
+- shared title typography and header border/divider baseline
+- shared collapsible body pattern
+- adaptive collapse direction logic and direction-aware collapse icons
+- migration of `tv-panel` and `news-panel`
+
+That keeps risk low while giving the rest of the HUD a stable target to migrate toward.

+# 智能星球 UE5 客户端一期实施方案（融合版）
+
+> 版本：v2.0  
+> 日期：2026-04-14  
+> 目标：把现有 Web Earth 项目，平滑推进到 **UE5 可用 MVP 客户端**  
+> 适用对象：**UE 零基础新手**  
+> 输出结果：一份 **能直接照着做** 的实施手册  
+> 策略：**保留原 MVP 方案里适合入门的部分，吸收更稳的工程做法，降低你第一次做 UE 时踩坑概率**
+
+---
+
+## 一、这份融合版方案解决什么问题
+
+你原来的 MVP 方案是靠谱的，优点很明显：
+
+- 范围克制
+- 适合新手入门
+- 目标明确
+- 能较快做出“看得见、点得到”的成果
+
+但它也有几个风险：
+
+- 默认 `localhost` 一定通，这在 WSL2 + Windows + Docker 环境里不一定成立
+- 默认 UE 蓝图里直接做 HTTP + JSON 解析会很顺，这一步其实很容易卡
+- 默认“一上来就接真实后端”，新手会同时踩 UE、Cesium、网络、JSON、蓝图五个坑
+- 时间估计略乐观
+
+所以这份融合版方案的核心思路是：
+
+## 核心原则
+
+**先做“本地数据可交互地球”，再做“真实后端对接”。**
+
+也就是把一期再拆成两个更稳的里程碑：
+
+### 里程碑 A：本地演示版
+先不接后端，只做：
+
+- UE5 项目能打开
+- Cesium 地球能显示
+- 本地 JSON 里的点能正确落到地球
+- 点击点能弹信息卡
+- HUD 能正常显示假状态
+
+### 里程碑 B：后端接入版
+在 A 的基础上再做：
+
+- HTTP 拉取真实后端数据
+- 显示真实 TOP500 数据
+- 显示后端在线状态
+- 为后续扩展海缆/BGP/卫星打基础
+
+这样做的好处是：
+
+- 把问题拆开
+- 更容易调试
+- 更适合 UE 新手
+- 不会因为后端联调没通就把整个 UE 开发节奏打断
+
+---
+
+# 二、一期目标：做什么，不做什么
+
+## 这次一期一定要做的
+
+做一个 **可用的 UE5 客户端 MVP**，达到以下 6 项：
+
+1. 能打开 UE 项目并看到 3D 地球
+2. 能在地球上显示超算数据点
+3. 能点击数据点弹出信息卡
+4. 能显示一个基础 HUD
+5. 能通过 HTTP 接入后端数据
+6. 能打包成 Windows 可执行程序
+
+---
+
+## 这次一期先不做的
+
+这些全部放到后续阶段：
+
+- 海缆路径渲染
+- 卫星轨迹与卫星图层
+- BGP 图层
+- WebSocket 实时更新
+- 粒子特效大升级
+- 自动巡航
+- 多屏/3D 偏振/大屏联动
+
+一句话：
+
+**一期不是“把 Web Earth 全搬到 UE”，而是“证明 UE 客户端链路能跑通”。**
+
+---
+
+# 三、UE 专有名词字典（零基础版）
+
+这部分你最好先读一遍。后面所有步骤都围绕这些词。
+
+## 1. Actor
+**Actor = 场景里的一个对象**
+
+你可以把它理解成：
+
+- 一个地球控制器
+- 一个超算点
+- 一台相机
+- 一条海缆
+
+这些在 UE 里都可以是 Actor。
+
+---
+
+## 2. Component
+**Component = 挂在 Actor 身上的功能零件**
+
+比如一个超算点 Actor，可能有：
+
+- 一个球形外观
+- 一个碰撞盒
+- 一个标签
+- 一个发光效果
+
+这些零件就是 Component。
+
+一句话：
+
+**Actor 是整台机器，Component 是机器上的零件。**
+
+---
+
+## 3. Blueprint（蓝图）
+**Blueprint = UE 的可视化编程系统**
+
+你不用先写代码，而是把很多“逻辑节点”拖出来，用线连接起来。
+
+你可以把它理解成：
+
+- 前端里的函数 + 事件监听
+- 只不过不是写文本代码，而是连线
+
+---
+
+## 4. Level / Map（关卡）
+**Level = 一个场景文件**
+
+你可以把它理解成 Three.js 的一个 Scene。
+
+本期只需要一个主场景：
+
+- `Main`
+
+---
+
+## 5. Widget / UMG
+**Widget = UI 组件**
+**UMG = UE 的 UI 编辑系统**
+
+比如：
+
+- 信息卡
+- 状态栏
+- 右上角连接状态
+- 图例
+- HUD 面板
+
+这些都用 Widget 做。
+
+---
+
+## 6. Material（材质）
+**Material = 决定物体外观的系统**
+
+比如：
+
+- 球体是什么颜色
+- 是否发光
+- 是否透明
+- 是否随性能大小变亮
+
+这些都由材质控制。
+
+---
+
+## 7. Static Mesh
+**Static Mesh = 不会变形的 3D 模型**
+
+比如：
+
+- 球
+- 立方体
+- 平面
+- 某个固定模型
+
+超算点一期里可以先直接用球体 Static Mesh。
+
+---
+
+## 8. Pawn
+**Pawn = 玩家控制的对象**
+
+一期里你可以把它理解成：
+
+- 带相机的飞行控制器
+
+---
+
+## 9. PlayerController
+**PlayerController = 处理输入的对象**
+
+比如：
+
+- 鼠标点击
+- 拖拽
+- 滚轮缩放
+
+这些都由 PlayerController 或其相关逻辑来处理。
+
+---
+
+## 10. GameMode
+**GameMode = 游戏/场景的主规则配置入口**
+
+它决定：
+
+- 默认用哪个 Pawn
+- 默认用哪个 PlayerController
+
+你可以把它理解成“主入口配置”。
+
+---
+
+## 11. Viewport
+**Viewport = 你看 3D 场景的窗口**
+
+就是 UE 编辑器中间那块 3D 视图。
+
+---
+
+## 12. Outliner
+**Outliner = 当前场景对象列表**
+
+你可以把它理解成：
+
+- Scene 树
+- DOM 树
+- 资源树
+
+---
+
+## 13. Details Panel
+**Details Panel = 选中对象后的属性面板**
+
+相当于“右侧属性编辑器”。
+
+---
+
+## 14. Cesium for Unreal
+**Cesium for Unreal = UE 里的地球插件**
+
+它负责：
+
+- 真实地球
+- 卫星影像
+- 地形
+- 经纬度坐标和 UE 世界坐标的转换
+
+如果没有它，你得自己处理地球和坐标系统，会非常难。
+
+---
+
+## 15. Struct（结构体）
+**Struct = 数据结构定义**
+
+你可以把它理解成 TypeScript 里的 `interface`。
+
+比如：
+
+```ts
+interface ComputePoint {
+  id: string
+  name: string
+  latitude: number
+  longitude: number
+  performance: number
+}
+```
+
+在 UE 里这类东西叫 Struct。
+
+---
+
+## 16. Event Dispatcher
+**Event Dispatcher = 事件分发器**
+
+你可以把它理解成：
+
+- EventEmitter
+- 发布订阅
+
+比如：
+
+“数据加载完毕”这个事件，就可以分发给其他蓝图。
+
+---
+
+## 17. Spline
+**Spline = 一条平滑曲线**
+
+后面做海缆、轨迹时非常有用。  
+一期可以先知道这个词，不一定马上用。
+
+---
+
+## 18. Niagara
+**Niagara = UE 粒子特效系统**
+
+比如：
+
+- 流光
+- 光晕
+- 拖尾
+- 火花
+
+一期先不重点碰它。
+
+---
+
+# 四、你的真实开发策略：两阶段起步
+
+这是这份融合版和原方案最大的区别。
+
+---
+
+## 阶段 A：本地演示版（先脱离后端）
+
+### 目标
+先把下面这些完全打通：
+
+- UE 项目启动正常
+- Cesium 地球正常
+- 相机可操作
+- 本地 JSON 文件能生成地球标记点
+- 点击点能弹信息卡
+- HUD 能显示假数据
+
+### 为什么一定要先做这个
+因为如果你一上来就接真实后端，你会同时碰到：
+
+- WSL2 到 Windows 网络
+- Docker 端口映射
+- UE HTTP 请求
+- 蓝图 JSON 解析
+- Cesium 坐标转换
+- 标记点生成
+
+新手很容易直接乱掉。
+
+---
+
+## 阶段 B：后端接入版（再联调）
+
+### 目标
+在 A 的基础上，加上：
+
+- HTTP 拉真实后端数据
+- 显示真实 TOP500 点
+- 右上角显示后端在线状态
+- 为后续做更多图层留下数据接入层
+
+---
+
+# 五、环境准备
+
+## 1. 你要安装的软件
+
+### Epic Games Launcher
+用来下载和启动 UE。
+
+### Unreal Engine 5.4
+建议直接用 5.4 稳定版。
+
+### Visual Studio 2022
+虽然一期主要用 Blueprint，但 UE 的很多项目依赖 VS 环境。
+
+安装组件：
+- Desktop development with C++
+- Game development with C++
+
+### Git
+用来管理文档和后续工程。
+
+### Cesium for Unreal
+用来做地球。
+
+---
+
+## 2. 你的环境约束
+
+你现在是：
+
+- 后端可能跑在 WSL2 / Docker
+- UE 必须跑在 Windows
+
+所以你的真实运行方式通常会是：
+
+- **Windows** 运行 UE5
+- **WSL2** 运行后端
+- 两者通过 HTTP 通信
+
+这里最关键的一条是：
+
+**不要默认 `localhost` 一定能通，必须先在 Windows 浏览器里验证。**
+
+---
+
+# 六、推荐的项目结构
+
+## UE 项目目录内的 Content 结构
+
+```text
+Content/
+  Blueprints/
+  Data/
+  Widgets/
+  Materials/
+  Levels/
+  FX/
+  Textures/
+```
+
+建议说明：
+
+- `Blueprints/` 放逻辑蓝图
+- `Data/` 放本地 JSON、DataTable、Struct
+- `Widgets/` 放 UI
+- `Materials/` 放材质
+- `Levels/` 放场景
+- `FX/` 放特效
+- `Textures/` 放贴图
+
+---
+
+# 七、一期最小蓝图清单
+
+一期只需要这几个核心蓝图。
+
+## 1. `BP_GlobeCamera`
+作用：相机控制器
+
+负责：
+- 鼠标拖拽旋转
+- 滚轮缩放
+- 初始视角控制
+
+---
+
+## 2. `BP_PlanetGameMode`
+作用：指定默认的 Pawn 等
+
+---
+
+## 3. `BP_DataLoader`
+作用：负责读数据
+
+一期建议支持两种来源：
+
+- 本地 JSON
+- HTTP 接口
+
+这样调试更稳。
+
+---
+
+## 4. `BP_ComputePoint`
+作用：一个超算点的显示对象
+
+负责：
+- 接收一条数据
+- 放到正确经纬度位置
+- 显示外观
+- 处理点击
+
+---
+
+## 5. `WBP_InfoCard`
+作用：点开后显示详情
+
+显示：
+- 名称
+- 国家
+- 算力
+- 可选显示更多字段
+
+---
+
+## 6. `WBP_StatusBar`
+作用：右上角状态栏
+
+显示：
+- 后端在线/离线
+- 当前加载条数
+- 当前模式（本地数据 / 真实后端）
+
+---
+
+# 八、数据层设计
+
+一期不要一开始就完全照搬后端返回结构。  
+你要先定义一个 UE 友好的结构。
+
+## `S_ComputePoint`
+
+字段建议：
+
+- `PointId`：字符串，唯一 ID
+- `Name`：字符串
+- `Latitude`：浮点
+- `Longitude`：浮点
+- `Performance`：浮点
+- `CoreCount`：整数
+- `Country`：字符串
+- `Source`：字符串
+
+这个结构同时适用于：
+
+- 本地 JSON
+- 后端 API 返回结果转换后的对象
+
+---
+
+# 九、最稳的执行路线
+
+下面是整个实施计划最重要的部分。
+
+---
+
+# Phase 0：安装和验证环境
+
+## 目标
+确保你能：
+
+- 安装 UE5.4
+- 启用 Cesium
+- 能打开一个空项目
+- 能在 Windows 浏览器访问你的后端
+
+## 验收
+满足以下 4 条：
+
+- UE 能打开
+- Cesium 能启用
+- 项目能创建
+- Windows 浏览器能访问后端 summary 接口
+
+如果第 4 条做不到，不要继续推进真实接口联调。
+
+---
+
+# Phase 1：创建项目并把地球显示出来
+
+## 目标
+打开项目后，能看到一个真实地球。
+
+## 操作顺序
+
+1. 新建 UE5 Blank Blueprint 项目
+2. 创建 `Main` 场景
+3. 启用 Cesium
+4. 添加：
+   - `Cesium World Terrain`
+   - `Cesium Sun Sky`
+   - `CesiumGeoreference`
+5. 调整视角，让你能看到整个地球
+
+## 验收
+能录一段短视频，里面能看到地球和镜头移动。
+
+---
+
+# Phase 2：做相机控制
+
+## 目标
+让地球可以：
+
+- 鼠标拖拽旋转
+- 滚轮缩放
+
+## 说明
+这里可以沿用原 MVP 方案的思路：
+
+- `BP_GlobeCamera` 作为 Pawn
+- Spring Arm + Camera 组成相机结构
+- 用输入控制旋转和缩放
+
+## 注意
+这一版相机只是“一期可用版”，不是最终镜头系统。
+
+## 验收
+按 Play 后：
+
+- 地球可旋转
+- 可缩放
+- 不会直接飞走或抖动失控
+
+---
+
+# Phase 3：先喂本地 JSON 数据
+
+这是融合版方案里最关键的改动。
+
+## 目标
+不接后端，先验证：
+
+- 数据结构正常
+- JSON 能读
+- 点能生成
+- 点击交互正常
+
+## 为什么先这么做
+因为这样可以把问题收缩成 3 件事：
+
+- Cesium 坐标转换
+- 点渲染
+- UI 弹窗
+
+不牵涉后端联调。
+
+## 本地 JSON 示例格式
+
+建议放在 `Content/Data/compute_points.json`
+

+]
+```
+
+## 推荐做法
+先做一个“本地模式”开关。
+
+在 `BP_DataLoader` 里支持：
+
+- Mode = LocalJson
+- Mode = HttpApi
+
+先永远跑 `LocalJson`。
+
+## 验收
+你应该能看到：
+
+- 多个点出现在地球上
+- 大致位置正确
+- 点击能弹信息卡
+
+---
+
+# Phase 4：做超算点蓝图
+
+## 目标
+完成 `BP_ComputePoint`
+
+每个点要实现：
+
+- 接收一条 `S_ComputePoint`
+- 经度纬度转成 UE 世界坐标
+- 在地球上显示为一个可见的发光球
+- 支持被点击
+
+## 显示建议
+
+### 外观
+先用最简单的球体 Static Mesh。
+
+### 材质
+做一个发光材质：
+
+- 红橙色
+- 自发光
+- 不追求复杂效果
+
+### 大小
+球体要足够大，确保在地球尺度下看得见。
+
+### 高度
+不要贴地表太近，建议悬浮在地表上方一个固定高度。
+
+## 验收
+同一批数据点在地球上的位置大体合理。
+
+---
+
+# Phase 5：做信息卡
+
+## 目标
+点击一个点后，弹出一个简单的信息卡。
+
+## `WBP_InfoCard` 要显示的内容
+建议只显示最关键的 3 个字段：
+
+- 名称
+- 国家
+- 算力
+
+一期先不要堆太多字段。
+
+## 验收
+点击点 → 卡片出现  
+点击关闭 → 卡片消失
+
+---
+
+# Phase 6：做基础 HUD
+
+## 目标
+屏幕上始终有一个简单状态栏。
+
+## `WBP_StatusBar` 显示内容建议
+- 当前模式：Local / HTTP
+- 已加载数据点数量
+- 后端状态：Unknown / Online / Offline
+
+在本地模式阶段，状态可以先写死或显示 `Local Demo`。
+
+## 验收
+不点击任何点时，屏幕右上角也有“系统正在工作”的感觉。
+
+---
+
+# Phase 7：再接真实后端
+
+这是第二阶段开始。
+
+## 目标
+把数据源从本地 JSON 切到 HTTP。
+
+## 正确做法
+不要把 `BP_DataLoader` 重写。  
+而是让它支持：
+
+- LocalJsonLoader
+- HttpLoader
+
+也就是：
+
+**显示层不变，只替换数据来源。**
+
+## 最重要的接口原则
+如果后端已有接口字段非常杂，不一定要 UE 直接吃。  
+可以加一个“更适合 UE 的轻量接口”。
+
+例如：
+
+`/api/v1/ue/bootstrap/top500`
+
+返回尽量扁平的数据：
+
+```json
+[
+  {
+    "PointId": "top500_1",
+    "Name": "Frontier",
+    "Latitude": 35.93,
+    "Longitude": -84.31,
+    "Performance": 1194.0,
+    "CoreCount": 8730624,
+    "Country": "US",
+    "Source": "top500"
+  }
+]
+```
+
+## 为什么推荐 UE 轻量接口
+因为 UE 不适合像前端 React 那样，层层解包一大堆复杂 JSON。
+
+---
+
+# Phase 8：做连接状态检测
+
+## 目标
+让 HUD 能显示：
+
+- 在线
+- 离线
+- 本地模式
+
+## 正确实现思路
+建议用一个很小的状态请求，比如：
+
+- summary 接口
+- health 接口
+- 或 UE 专用 ping 接口
+
+不要让状态检测去依赖一个超大的数据接口。
+
+## 验收
+后端关掉时，状态栏能明显变成 Offline。
+
+---
+
+# Phase 9：打包发布
+
+## 目标
+把项目打包成 Windows 可执行程序。
+
+## 注意
+打包是一期必须尝试的，但不要让它阻塞前面所有开发。
+
+也就是说：
+
+- 编辑器里没稳定跑通前，不要反复纠结打包
+- 等 LocalJson 版和 HTTP 版都能在编辑器 Play 模式稳定运行后，再打包
+
+## 验收
+双击 exe 可以运行，进入地球场景并正常展示数据。
+
+---
+
+# 十、建议的 14 天执行计划
+
+这版比原 MVP 的时间估计更保守，也更适合新手。
+
+## 第 1 天
+- 安装 UE5.4
+- 安装 Cesium
+- 创建空项目
+- 创建 Main 场景
+
+## 第 2 天
+- 启用 Cesium
+- 把地球跑起来
+- 保存项目结构
+
+## 第 3 天
+- 做 `BP_GlobeCamera`
+- 跑通旋转和缩放
+
+## 第 4 天
+- 建 `S_ComputePoint`
+- 准备本地 JSON 文件
+- 做 `BP_DataLoader` 的本地模式
+
+## 第 5 天
+- 做 `BP_ComputePoint`
+- 本地 JSON 批量生成点
+
+## 第 6 天
+- 调整点大小、颜色、高度
+- 检查经纬度位置是否大致正确
+
+## 第 7 天
+- 做 `WBP_InfoCard`
+- 跑通点击点弹卡片
+
+## 第 8 天
+- 做 `WBP_StatusBar`
+- 显示本地模式状态和点数量
+
+## 第 9 天
+- Windows 浏览器验证后端接口
+- 准备 HTTP 版加载逻辑
+
+## 第 10 天
+- 实现 HTTP 拉真实数据
+- 先在日志里确认数据到了
+
+## 第 11 天
+- 把 HTTP 数据接到点渲染
+- 切换 Local / HTTP 两种模式
+
+## 第 12 天
+- 做连接状态 Online / Offline
+- 补错误提示
+
+## 第 13 天
+- 测试完整链路
+- 修点选、缩放、HUD 细节
+
+## 第 14 天
+- 进行第一次打包
+- 在 Windows 下运行 exe 验证
+
+---
+
+# 十一、这份方案和原 MVP 方案怎么融合
+
+下面是合并关系。
+
+## 保留原 MVP 方案的部分
+这些内容很好，建议继续用：
+
+- 术语表
+- Phase 结构化写法
+- `BP_GlobeCamera`
+- `BP_ComputePoint`
+- `WBP_InfoCard`
+- `WBP_StatusBar`
+- 相机、点、信息卡、状态栏这 4 个核心对象
+- “先别做海缆、卫星、BGP”的范围控制
+
+## 用融合版修正的部分
+这些是这份新文档加进去的：
+
+- 两阶段起步：先本地 JSON，再真实后端
+- 不默认 `localhost` 一定通
+- 推荐做 UE 轻量接口，而不是死扛原始接口
+- 把打包放到后段，而不是过早纠结
+- 时间预估更保守
+- 明确“一期只是证明链路跑通”
+
+---
+
+# 十二、验收清单
+
+## 环境
+- [ ] UE5.4 安装成功
+- [ ] Cesium 插件启用成功
+- [ ] Windows 能访问后端接口
+
+## 本地演示版
+- [ ] 地球渲染正常
+- [ ] 鼠标可旋转和缩放
+- [ ] 本地 JSON 数据能生成点
+- [ ] 点的位置大体正确
+- [ ] 点击点能弹信息卡
+- [ ] HUD 可显示本地模式和点数量
+
+## 后端接入版
+- [ ] HTTP 能拉取真实数据
+- [ ] HTTP 数据能生成点
+- [ ] HUD 能显示 Online/Offline
+- [ ] 切换 Local / HTTP 模式不崩
+- [ ] exe 能打包并运行
+
+---
+
+# 十三、后续路线（MVP 之后）
+
+当这一期做完后，下一步顺序建议是：
+
+1. 海缆路径
+2. 卫星点或轨迹
+3. 更稳的相机与巡航
+4. WebSocket 增量更新
+5. BGP 区域态势
+6. BGP 事件点
+7. 更强的粒子和视觉风格
+
+也就是说：
+
+**先补“静态层和镜头层”，再补“高频实时层”。**
+
+---
+
+# 十四、一句话总结
+
+这份融合版方案的核心就是：
+
+**保留原 MVP 的入门友好度，但改成“先本地 JSON、再真实后端”的两阶段实施路线，让你第一次做 UE 时更稳、更容易成功。**
+
+如果你按这份方案推进，一期最现实的目标不是“立刻做出完整 UE 大屏”，而是：
+
+**在 14 天左右，做出一个能显示真实地球、能显示超算点、能点击看详情、能接后端的可用 UE 客户端 MVP。**
