3. PlatformIO 官方文档（构建/依赖/上传）
   [https://docs.platformio.org/](vscode-file://vscode-app/d:/SoftwareInstall/MicrosoftVSCode/Microsoft VS Code/resources/app/out/vs/code/electron-browser/workbench/workbench.html)
4. ESP-IDF 文档（你代码里 esp_http_server、底层类型会用到）
   [https://docs.espressif.com/projects/esp-idf/en/latest/esp32/](vscode-file://vscode-app/d:/SoftwareInstall/MicrosoftVSCode/Microsoft VS Code/resources/app/out/vs/code/electron-browser/workbench/workbench.html)
5. esp32-camera 官方仓库（图传与摄像头参数）
   [https://github.com/espressif/esp32-camera](vscode-file://vscode-app/d:/SoftwareInstall/MicrosoftVSCode/Microsoft VS Code/resources/app/out/vs/code/electron-browser/workbench/workbench.html)
6. ESP32Servo 库

• 看：Arduino Reference 对应条目
• 产出：能解释每个初始化语句作用

Day 3：Wi-Fi AP 模式

• 学：[WiFi.mode(WIFI_AP)](vscode-file://vscode-app/d:/SoftwareInstall/MicrosoftVSCode/Microsoft VS Code/resources/app/out/vs/code/electron-browser/workbench/workbench.html)、[WiFi.softAP()](vscode-file://vscode-app/d:/SoftwareInstall/MicrosoftVSCode/Microsoft VS Code/resources/app/out/vs/code/electron-browser/workbench/workbench.html)、[WiFi.softAPIP()](vscode-file://vscode-app/d:/SoftwareInstall/MicrosoftVSCode/Microsoft VS Code/resources/app/out/vs/code/electron-browser/workbench/workbench.html)
• 看：Arduino-ESP32 WiFi 章节
• 产出：说清“为什么手机能直连小车热点”

Day 4：摄像头链路

• 学：[camera_config_t](vscode-file://vscode-app/d:/SoftwareInstall/MicrosoftVSCode/Microsoft VS Code/resources/app/out/vs/code/electron-browser/workbench/workbench.html)、[esp_camera_init()](vscode-file://vscode-app/d:/SoftwareInstall/MicrosoftVSCode/Microsoft VS Code/resources/app/out/vs/code/electron-browser/workbench/workbench.html)、帧尺寸/质量/PSRAM关系
• 看：esp32-camera 示例与 README
• 产出：理解 FRAMESIZE、jpeg_quality、fb_count 的取舍

Day 5：HTTP 控制模型
