Walkthrough

This PR introduces a custom Confirmation Dialog System to replace native window.confirm() calls. It includes a promise-based useConfirm hook, a reusable ConfirmDialog component with dual-theme support, context provider integration, and migration of existing confirmation flows in GroupDetails to use the new system.

Integration & Application Setup
web/App.tsx, web/pages/GroupDetails.tsx
App.tsx wrapped AppRoutes with ConfirmProvider. GroupDetails replaced all window.confirm() calls with async useConfirm() hook for delete, leave, and remove member actions.
Dependencies
web/package.json
Added @types/react and @types/react-dom TypeScript type definitions.
Documentation & Project Management
.Jules/changelog.md, .Jules/knowledge.md, .Jules/todo.md
Updated changelog with feature summary, added Confirmation Dialog Pattern documentation, and marked destructive action confirmation task as completed.

hardcoded Tailwind classes (`bg-red-100`, `bg-blue-100`, `text-red-600`,
`text-blue-600`) which don't respect the app theme; update the ConfirmDialog
component to call useTheme() (same hook used by Button/Modal), derive
theme-aware background/text classes based on isDanger and the returned theme
value, and apply those computed classes to the icon container div (the element
that currently builds className with isDanger). Ensure the logic handles both
danger/normal states and maps to the theme's glass/neobrutalism class tokens so
the AlertTriangle/Info icon colors adapt with the rest of the UI.

message element has the matching id so screen readers associate the description;
also change autofocus so when isDanger is true the cancel Button gets autoFocus

⚠️ Potential issue | 🟡 Minor

Missing role="alertdialog" and aria-describedby for accessibility.

The PR objectives state accessibility support via role="alertdialog", but this isn't implemented. For alert dialogs, the ARIA role should be set on the dialog container, and focus management should trap focus within the dialog. Additionally, consider placing autoFocus on the cancel button for danger variants to prevent accidental destructive actions.
,

Suggested accessibility improvements

The Modal component should receive ARIA attributes. If Modal doesn't support passing these through, consider wrapping the content or enhancing Modal. At minimum, for alert dialogs:

     <Modal
       isOpen={isOpen}
       onClose={onCancel}
       title={title}
+      role="alertdialog"
+      aria-describedby="confirm-dialog-message"
       footer={
         <>
           <Button variant="ghost" onClick={onCancel}>
             {cancelText}
           </Button>
           <Button
             variant={isDanger ? 'danger' : 'primary'}
             onClick={onConfirm}
-            autoFocus
+            autoFocus={!isDanger}
           >
             {confirmText}
           </Button>
         </>
       }
     >

And add the id to the message:

-          <p className="text-base opacity-90 leading-relaxed">{message}</p>
+          <p id="confirm-dialog-message" className="text-base opacity-90 leading-relaxed">{message}</p>

🧹 Nitpick | 🔵 Trivial

Icon container styling doesn't adapt to themes.

The icon background uses hardcoded colors (bg-red-100, bg-blue-100) that don't integrate with the Glassmorphism/Neobrutalism theme system. Both Button and Modal components use useTheme() to adapt styling. For visual consistency, this component should also adapt.

Theme-aware icon styling example
+import { useTheme } from '../../contexts/ThemeContext';
+import { THEMES } from '../../contexts/ThemeContext';
...
+  const { style } = useTheme();
+
+  const iconContainerStyles = style === THEMES.NEOBRUTALISM
+    ? isDanger
+      ? 'bg-red-500 text-white border-2 border-black'
+      : 'bg-blue-500 text-white border-2 border-black'
+    : isDanger
+      ? 'bg-red-100 text-red-600'
+      : 'bg-blue-100 text-blue-600';
...
         <div
-          className={`p-3 rounded-full flex-shrink-0 ${
-            isDanger ? 'bg-red-100 text-red-600' : 'bg-blue-100 text-blue-600'
-          }`}
+          className={`p-3 rounded-full flex-shrink-0 ${iconContainerStyles}`}

⚠️ Potential issue | 🟠 Major

Concurrent confirm() calls can cause promises to hang indefinitely.

If confirm() is called while a dialog is already open, the previous resolvePromise is overwritten without being resolved. This leaves the prior caller's Promise pending forever, potentially causing UI hangs or memory leaks if the caller is awaiting.

Suggested fix: reject or resolve previous promise before opening new dialog
   const confirm = useCallback((options: ConfirmOptions) => {
+    // Resolve any pending promise as cancelled before opening new dialog
+    if (resolvePromise) {
+      resolvePromise(false);
+    }
     setOptions(options);
     setIsOpen(true);
     return new Promise<boolean>((resolve) => {
       setResolvePromise(() => resolve);
     });
-  }, []);
+  }, [resolvePromise]);

Alternatively, you could queue confirmations or reject with an error if already open:

const confirm = useCallback((options: ConfirmOptions) => {
  if (isOpen) {
    return Promise.resolve(false); // or throw new Error('Dialog already open')
  }
  // ... rest of implementation
}, [isOpen]);

🧹 Nitpick | 🔵 Trivial

Consider clearing resolvePromise after resolution.

After resolving the promise, resolvePromise remains set to the old resolver function. While this doesn't cause immediate issues because isOpen guards the dialog, clearing it provides cleaner state management and prevents potential edge cases.

   const handleConfirm = useCallback(() => {
     if (resolvePromise) resolvePromise(true);
     setIsOpen(false);
+    setResolvePromise(null);
