• Credits support: scrapes ChatGPT usage page via WKWebView, shows remaining credits + history inline, and moves history to a submenu.
• Sign-in window with cookie reuse and a logout/clear-cookies action; waits out workspace picker and auto-navigates to usage page.
• Menu: credits line bolded; login prompt hides once credits load; debug toggle always visible (HTML dump).
• Icon: when weekly is empty, top bar becomes a thick credits bar (capped at 1k); otherwise bars stay 5h/weekly.
