## [Unreleased]
### Added
+- **Confirmation Dialog System:** Replaced browser's native `alert`/`confirm` with a custom, accessible, and themed modal system.
+ - **Features:**
+ - Dual-theme support (Glassmorphism & Neobrutalism).
+ - Asynchronous `useConfirm` hook returning a Promise.
+ - Specialized variants (danger, warning, info) with appropriate styling and icons.
+ - Fully accessible `Modal` component (added `role="dialog"`, `aria-labelledby`, `aria-modal`).
+ - **Technical:** Created `web/components/ui/ConfirmDialog.tsx`, `web/contexts/ConfirmContext.tsx`. Updated `web/pages/GroupDetails.tsx` to use the new system.
+
- **Error Boundary System:** Implemented a global React Error Boundary to catch render errors gracefully.
- **Features:**
- Dual-theme support (Glassmorphism & Neobrutalism) for the error fallback UI.

- Keyboard navigation support for Groups page, enabling accessibility for power users.
### Changed
+- **Web App:** Refactored `GroupDetails` destructive actions (Delete Group, Delete Expense, Leave Group, Remove Member) to use the new `ConfirmDialog` instead of `window.confirm`.
+- **Accessibility:** Updated `Modal` component to include proper ARIA roles and labels, fixing a long-standing accessibility gap.
- Updated JULES_PROMPT.md based on review of successful PRs:
- Emphasized complete system implementation over piecemeal changes
- Added best practices from successful PRs (Toast system, keyboard navigation iteration)

## Component Patterns
+### Confirmation Dialog System
+
+**Date:** 2026-01-21
+**Context:** Replacing window.confirm with accessible modal
+
+To handle destructive actions asynchronously while maintaining UI consistency:
+
+```tsx
+// 1. Setup in App
+
+
+
+
+// 2. Usage in Component
+const { confirm } = useConfirm();
+
+const handleDelete = async () => {
+ const result = await confirm({
+ title: 'Delete Item',
+ description: 'Are you sure?',
+ variant: 'danger', // danger | warning | info
+ confirmText: 'Delete'
+ });
+
+ if (result) {
+ await deleteItem();
+ }
+}
+```
+
+**Key Implementation Detail:**
+Uses a promise-based approach (`new Promise(resolve => ...)`) stored in state/ref to bridge the imperative `confirm()` call with the declarative React UI rendering.

## Recent Implementation Reviews
+### ✅ Successful PR Pattern: Confirmation Dialog System (#255)
+
+**Date:** 2026-01-21
+**Context:** Replacing native confirm dialogs with custom UI
+
+**What was implemented:**
+1. Created `ConfirmContext` using Promise pattern for async/await usage
+2. Created `ConfirmDialog` component wrapping existing `Modal`
+3. Enhanced `Modal` with proper ARIA attributes (`role="dialog"`, `aria-labelledby`)
+4. Replaced native `window.confirm` in `GroupDetails.tsx`
+
+**Why it succeeded:**
+- ✅ Improved UX (no more native browser alerts)
+- ✅ Improved Accessibility (Modal roles + keyboard support)
+- ✅ Maintained dual-theme support (Glass/Neo)
+- ✅ Clean integration via Context API (easy to use `const { confirm } = useConfirm()`)
+
+**Key learnings:**
+- Modals need explicit ARIA roles to be testable/accessible.
+- Promise-based context API allows keeping the call site logic simple (`if (await confirm()) ...`).
