切換不同主題面板時不再閃爍，而且瞬間出現
在切換不同的面板主題時，畫面變得非常滑順。以前每次換面板，系統都會把整個視窗關掉重開、而且會先露出底下的深色背景閃一下；現在系統會把你開過的面板（最多記 6 個）悄悄藏在背後，切換時只負責把最新的數字填進去再端出來。所以只要是開過的面板，切換過去就是瞬間出現，沒有任何閃爍，連視窗都不用關閉重開。就像換佈景，以前是把整個舞台布幕拉下來拆掉重裝，現在是舞台底下早就準備好多個旋轉舞台，轉過來就能直接演。

BUGFIX
Switching theme panels is now instant and flicker-free
Switching between different theme panels is now incredibly smooth. Previously, every time you switched panels, the system would tear down and reopen the entire window, exposing the dark background for a split-second flicker. Now, the system quietly keeps the panels you've opened (up to 6) waiting in the background. When you switch, it simply injects the latest numbers and brings the panel to the front. This means any previously opened panel reappears instantly with zero flickering, and the window itself never closes and reopens. It's like changing theatre sets: instead of dropping the curtain and tearing down the whole stage, they now have multiple rotating stages fully prepared underneath, seamlessly spinning into place ready for the next act.
原始 CHANGELOG
Original changelog切換不同主題面板時不再閃爍，而且瞬間出現
**Switching panels no longer flickers**: every switch tore down the WKWebView and reloaded its HTML, exposing the dark backing layer until the load finished — a visible flicker, plus the popover closed and reopened. usage now caches each panel's web view (lazily, capped at 6 with LRU eviction) inside a container view and switches by toggling visibility and re-injecting the latest state, so a previously-opened panel reappears instantly with no reload. The first build of a panel fades in from a same-color overlay that is removed on the first successful paint (or after a 1.5s safety timeout). The popover no longer closes and reopens on switch.
