+# ConfirmDialog - Accessible Confirmation Dialog
+
+## Overview
+
+`ConfirmDialog` standardizes confirmation flows across the app. It replaces ad‑hoc `window.confirm` usage with an accessible, themeable dialog that supports asynchronous operations.
+
+## Key Features
+
+### 1. Accessibility & UX
+- Uses shared `Dialog` primitives (focus trap, ARIA roles)
+- Blocks dismissal while async confirm is pending
+- Clear separation of title (action) vs description (context)
+
+### 2. Async-Aware
+- Accepts sync or async `onConfirm`
+- Auto-closes on resolve; remains open on error for retry / toast
+
+### 3. Internationalization Ready
+- All labels / text provided by caller through i18n hook
+- Supports interpolation for dynamic context
+
+### 4. Minimal Surface, Easy Extension
+- Lightweight API (few required props)
+- Style hook via `.container` class (SCSS module)
+
+## Architecture
+
+```
+ConfirmDialog
+├── State: loading (tracks pending confirm action)
+├── Dialog primitives: Header (title + description), Footer (buttons)
+└── External control: parent owns open state via onOpenChange
+```
+
+## Usage
+
+```tsx
+import { useTranslate } from "@/utils/i18n";
+import ConfirmDialog from "@/components/ConfirmDialog";
+
+const t = useTranslate();
+
+<ConfirmDialog
+  open={open}
+  onOpenChange={setOpen}
+  title={t("memo.delete-confirm")}
+  description={t("memo.delete-confirm-description")}
+  confirmLabel={t("common.delete")}
+  cancelLabel={t("common.cancel")}
+  onConfirm={handleDelete}
+  confirmVariant="destructive"
+/>;
+```
+
+## Props
+
+| Prop | Type | Required | Acceptable Values |
+|------|------|----------|------------------|
+| `open` | `boolean` | Yes | `true` (visible) / `false` (hidden) |
+| `onOpenChange` | `(open: boolean) => void` | Yes | Callback receiving next state; should update parent state |
+| `title` | `React.ReactNode` | Yes | Short localized action summary (text / node) |
+| `description` | `React.ReactNode` | No | Optional contextual message |
+| `confirmLabel` | `string` | Yes | Non-empty localized action text (1–2 words) |
+| `cancelLabel` | `string` | Yes | Localized cancel label |
+| `onConfirm` | `() => void | Promise<void>` | Yes | Sync or async handler; resolve = close, reject = stay open |
+| `confirmVariant` | `"default" | "destructive"` | No | Defaults to `"default"`; use `"destructive"` for irreversible actions |
+
+## Benefits vs Previous Implementation
+
+### Before (window.confirm / ad‑hoc dialogs)
+- Blocking native prompt, inconsistent styling
+- No async progress handling
+- No rich formatting
+- Hard to localize consistently
+
+### After (ConfirmDialog)
+- Unified styling + accessibility semantics
+- Async-safe with loading state shielding
+- Plain description flexibility
+- i18n-first via externalized labels
+
+## Technical Implementation Details
+
+### Async Handling
+```tsx
+const handleConfirm = async () => {
+  setLoading(true);
+  try {
+    await onConfirm(); // resolve -> close
+    onOpenChange(false);
+  } catch (e) {
+    console.error(e); // remain open for retry
+  } finally {
+    setLoading(false);
+  }
+};
+```
+
+### Close Guard
+```tsx
+<Dialog open={open} onOpenChange={(next) => !loading && onOpenChange(next)} />
+```
+
+## Browser / Environment Support
+- Works anywhere the existing `Dialog` primitives work (modern browsers)
+- No ResizeObserver / layout dependencies
+
+## Performance Considerations
+1. Minimal renders: loading state toggles once per confirm attempt
+2. No portal churn—relies on underlying dialog infra
+
+## Future Enhancements
+1. Severity icon / header accent
+2. Auto-focus destructive button toggle
+3. Secondary action (e.g. "Archive" vs "Delete")
+4. Built-in retry / error slot
+5. Optional checkbox confirmation ("I understand the consequences")
+6. Motion/animation tokens integration
+
+## Styling
+The `ConfirmDialog.module.scss` file provides a `.container` hook. It currently only hosts a harmless custom property so the stylesheet is non-empty. Add real layout or variant tokens there instead of inline styles.
+
+## Internationalization
+All visible strings must come from the translation system. Use `useTranslate()` and pass localized values into props. Separate keys for title/description.
+
+## Error Handling
+Errors thrown in `onConfirm` are caught and logged. The dialog stays open so the caller can surface a toast or inline message and allow retry. (Consider routing serious errors to a higher-level handler.)
+
+---
+
+If you extend this component, update this README to keep usage discoverable.
