 6. **移动端复制**：非 HTTPS 环境 `navigator.clipboard` 不可用，`useClipboard` 已内置 `execCommand` 回退，不要重写复制逻辑。
 7. **JSON.parse 的输入**：Vue `v-model` 绑定 textarea 的是字符串；解析前先 `trim()` 判空，错误信息取 `e.message` 展示给用户。
+8. **t-slider 的 label**：类型是 `string | boolean | TNode`，**不能传函数 formatter**（历史 bug）；百分比文案用外部 `<span>` 显示。
+9. **PNG 无损**：canvas 的 PNG 编码忽略 quality 参数，`browser-image-compression` 对 PNG 只能靠迭代降质量（无效）；「限制大小」模式对 PNG 基本不生效，UI 已提示改用 JPG/WebP。
+10. **透明图转 JPG 变黑**：浏览器 canvas 把透明区编码为 JPG 时填黑色；必须先画白底再压缩（`flattenToWhite` 顺序不能反，先压缩透明区已被填黑不可恢复）。
+11. **历史文本解析**：图片压缩/裁剪的历史按结构化文本保存（如 `q=0.8 | type=jpeg | max=1920`），用正则 `q=([\d.]+)` 等解析；不要用 `\| jpg` 这类含空分支的正则（`/| jpg/` 恒为 true，是历史 bug）。
