+- Add: Session Diary section showing 5h burn rate history sparkline
-- Fixed: script results now use window.chrome.webview.postMessage instead of async IIFE return value — older WebView2 runtimes don't await Promises from ExecuteScriptAsync, so data was never received
+- Add: Extra Usage Credits section showing spent/limit/balance (when enabled)
-- Debug text in Settings will now always show what happened during sign-in
