# Shot Delete Dialog - Alert Components Update

## Overview

Updated the `ShotDeleteConfirmDialog.vue` component to use shadcn-vue Alert components for all warning and informational messages, replacing custom styled divs with proper semantic alert components.

## Changes Made

### 1. Replaced Custom Alert Styling with shadcn-vue Alert Components

**Before:**
```vue
<!-- Error State -->
<div class="rounded-lg border border-destructive/20 bg-destructive/5 p-4">
  <div class="flex items-center gap-2 mb-2">
    <AlertCircle class="h-4 w-4 text-destructive" />
    <span class="font-medium text-destructive">Failed to load deletion information</span>
  </div>
  <p class="text-sm text-muted-foreground">{{ loadError }}</p>
</div>
```

**After:**
```vue
<!-- Error State -->
<Alert variant="destructive">
  <AlertCircle class="h-4 w-4" />
  <AlertTitle>Failed to load deletion information</AlertTitle>
  <AlertDescription>{{ loadError }}</AlertDescription>
</Alert>
```

### 2. Updated All Alert Types

#### Error Messages
- Uses `Alert` with `variant="destructive"`
- Includes `AlertTitle` and `AlertDescription` for proper semantic structure
- Icon positioning handled automatically by the Alert component

#### Warning Messages (Affected Users)
- Uses `Alert` with custom styling classes for orange warning appearance
- Maintains the same visual design but with proper Alert component structure
- Preserves the user list display within `AlertDescription`

#### Success Messages (No Affected Users)
- Uses `Alert` with custom styling classes for green success appearance
- Simple message display using `AlertDescription`

#### Information Messages (Data Preservation)
- Uses `Alert` with custom styling classes for blue info appearance
- Includes both `AlertTitle` and `AlertDescription` for structured content

### 3. Added Component Imports

```vue
import {
  Alert,
  AlertDescription,
  AlertTitle,
} from '@/components/ui/alert'
```

### 4. Code Cleanup

- Removed unused `onMounted` import from ShotDeleteConfirmDialog.vue
- Removed unused `computed` import from ShotsDataTable.vue
- Fixed TypeScript/linting warnings

## Benefits

### 1. Consistency
- All alerts now use the same shadcn-vue Alert component system
- Consistent styling and behavior across the application
- Proper semantic HTML structure with ARIA roles

### 2. Accessibility
- Alert components include proper `role="alert"` attributes
- Better screen reader support with structured titles and descriptions
- Consistent focus management and keyboard navigation

### 3. Maintainability
- Centralized alert styling through shadcn-vue components
- Easier to update alert appearance globally
- Reduced custom CSS and styling inconsistencies

### 4. Design System Compliance
- Follows shadcn-vue design system patterns
- Consistent with other UI components in the application
- Better integration with theme system

## Alert Component Variants Used

### Destructive Variant
```vue
<Alert variant="destructive">
  <AlertCircle class="h-4 w-4" />
  <AlertTitle>Error Title</AlertTitle>
  <AlertDescription>Error message details</AlertDescription>
</Alert>
```

### Default Variant with Custom Styling
```vue
<Alert variant="default" class="border-orange-200 bg-orange-50">
  <Users class="h-4 w-4 text-orange-600" />
  <AlertTitle class="text-orange-800">Warning Title</AlertTitle>
  <AlertDescription class="text-orange-700">Warning message</AlertDescription>
</Alert>
```

## Visual Impact

The visual appearance remains the same for users, but the underlying implementation is now:
- More semantic and accessible
- Consistent with the design system
- Easier to maintain and update
- Better structured for screen readers

## Testing

Created `frontend/test-shot-delete-alert-components.html` to verify:
