Unsaved changes in the Studio editor are lost. Only data you saved to project or library survives.
编辑器里未保存的改动会丢失。只有保存到项目或素材库的数据会保留。
1. Before closing, click save in project to store the current panels and codes.
1. 关闭前先在项目里保存，存储当前面板与编码。
2. Save reusable assets one by one: open LIBRARY and save actions, music, schedules, or events to the server library.
2. 逐个保存可复用素材：打开 LIBRARY，把动作、音乐、排程、事件保存到服务器素材库。
3. If you only need the preview, finish in CANVAS first; canvas edits sync back into codes but are not persisted until you save.
3. 若只需预览，先在 CANVAS 完成；画布改动会同步回编码，但保存前不会持久化。
4. Run whole-project validation with a click; fix red errors from the clickable list, then save again.
4. 一键执行整项目校验，按可点击错误列表修正红色错误，再次保存。
