Architecture / 架构

memo-wallpaper.html    ← 前端编辑器（浏览器打开，操作事件）
wallpaper_engine.py    ← 后端引擎（Python HTTP 服务 + 壁纸渲染）
launch_wallpaper.py    ← 一键启动器（无边框浏览器窗口）

• The HTML editor communicates with the Python engine via REST API on 127.0.0.1:8899
• The engine renders events onto a BMP image and sets it as the Windows wallpaper
• Events persist in %APPDATA%/memo-wallpaper/events.json
