Usage 0.6.2

之前在駭客任務（Matrix）面板裡，「專案用量」卡片上的資料夾圖示不見了。這是因為程式碼裡不小心寫了一段無限迴圈的顏色設定（CSS 變數自己參考自己），導致系統不知所措，直接把圖示變成透明的。我們現在把那段多餘的設定移除了，資料夾圖示就正常顯示了。就像是油漆工不小心把顏料罐的標籤貼成了「這罐顏料的顏色」，結果不知道該塗什麼顏色就乾脆不塗，現在把亂標的標籤撕掉，終於塗上正確的顏色了。

Previously, on the Matrix panel, the folder icon on the "Project Usage" card disappeared. This happened because a cyclic color setting (a CSS variable referencing itself) was accidentally written into the code, causing the system to throw its hands up and render the icon completely transparent. We have now removed that redundant setting, and the folder icon displays normally again. It's like a painter accidentally labeling a paint can "the color of this paint" and ending up painting nothing out of confusion; now that the bad label is peeled off, the correct color is finally applied.
