**Status:** Ready for Review

## Epic Reference
**Epic 9:** Design & Branding Implementation

## User Story
As a **visitor**,
I want **to see the Libra scales logo prominently displayed**,
So that **I recognize the firm's branding**.

## Dependencies

- **Note:** Footer integration deferred to Story 9.7; Email templates to Epic 8

## Acceptance Criteria

### Logo Placement
- [x] Navigation: Top left (desktop), centered (mobile)
- [ ] Footer: Smaller version (integrated when footer created in Story 9.7)
- [ ] Email templates: Header (integrated when email templates created in Epic 8)
- [ ] PDF exports: Header (integrated when PDF exports created)

### Logo Specifications
- [x] Minimum size: 120px width (desktop), 80px width (mobile)
- [x] Clear space: 20px padding minimum around logo

### Format Support
- [x] SVG primary (scalable, preferred)
- [x] PNG fallback (for email clients that don't support SVG)

### Color Variations
- [x] **Full color:** Gold (#D4AF37) logo on Navy (#0A1F44) background
- [x] **Reversed:** Navy (#0A1F44) logo on light/cream (#F9F7F4) background
- [x] **Monochrome:** Single-color gold (#D4AF37) version

### Features
- [x] Responsive sizing based on viewport
- [x] Accessible alt text: "Libra Law Firm" (translatable)

## Technical Notes

### Existing Component
An `app-logo.blade.php` component already exists at `resources/views/components/app-logo.blade.php`. This story will **replace** it with a more robust implementation supporting variants and sizes.

**Files to modify:**
- `resources/views/components/app-logo.blade.php` - Replace with new implementation
- `resources/views/components/app-logo-icon.blade.php` - Update or remove
- `resources/views/components/layouts/app/header.blade.php` - Update logo usage (lines 11, 96)

**Files to create:**
- `public/images/logo.svg` - Full color logo
- `public/images/logo-reversed.svg` - Reversed color logo
- `public/images/logo-mono.svg` - Monochrome logo
- `public/images/logo.png` - PNG fallback

### Logo Component Implementation

```blade
<!-- resources/views/components/app-logo.blade.php -->
@props([
    'size' => 'default',
    'variant' => 'full',
    'showText' => true
])

@php
$sizes = [
    'small' => 'h-8 min-w-[80px]',      // Mobile minimum
    'default' => 'h-12 min-w-[120px]',  // Desktop default
    'large' => 'h-16 min-w-[160px]',    // Large displays
];

$variants = [
    'full' => 'logo.svg',
    'reversed' => 'logo-reversed.svg',
    'mono' => 'logo-mono.svg',
];

$sizeClass = $sizes[$size] ?? $sizes['default'];
$logoFile = $variants[$variant] ?? $variants['full'];
@endphp

<div {{ $attributes->merge(['class' => 'flex items-center gap-2 p-5']) }}>
    <img
        src="{{ asset('images/' . $logoFile) }}"
        alt="{{ __('Libra Law Firm') }}"
        class="{{ $sizeClass }} w-auto object-contain"
        onerror="this.onerror=null; this.src='{{ asset('images/logo.png') }}';"
    />
    @if($showText)
        <span class="font-semibold text-sm truncate">{{ __('Libra Law Firm') }}</span>
    @endif
</div>
```

### Logo Asset Fallback Strategy
If final logo assets are not yet available:
1. Create a placeholder SVG using Libra scales icon from Heroicons or similar
2. Use the brand colors (Gold #D4AF37, Navy #0A1F44)
3. Replace with final assets when provided

### Color Reference (from Story 9.1)
| Color | Hex | Usage |
|-------|-----|-------|
| Dark Navy Blue | #0A1F44 | Primary background |
| Gold/Brass | #D4AF37 | Primary accent, logo |
| Off-White/Cream | #F9F7F4 | Light backgrounds |

## Testing Requirements

### Unit Tests
Create `tests/Feature/Components/LogoComponentTest.php`:

```php
<?php

use function Pest\Laravel\get;

test('logo component renders with default props', function () {
    $view = $this->blade('<x-app-logo />');

    $view->assertSee('Libra Law Firm');
    $view->assertSee('logo.svg');
});

test('logo component renders small size variant', function () {
    $view = $this->blade('<x-app-logo size="small" />');

    $view->assertSee('h-8');
});

test('logo component renders reversed color variant', function () {
    $view = $this->blade('<x-app-logo variant="reversed" />');

    $view->assertSee('logo-reversed.svg');
});

test('logo component renders without text when showText is false', function () {
    $view = $this->blade('<x-app-logo :showText="false" />');

    $view->assertDontSee('<span');
});

test('logo has accessible alt text', function () {
    $view = $this->blade('<x-app-logo />');

    $view->assertSee('alt="Libra Law Firm"', false);
});
```

### Browser Tests (Pest v4)
Create `tests/Browser/LogoTest.php`:

```php
<?php

it('displays logo in navigation on desktop', function () {
    $page = visit('/');

    $page->assertVisible('img[alt="Libra Law Firm"]')
         ->assertNoJavascriptErrors();
});

it('logo is responsive on mobile viewport', function () {
    $page = visit('/')
        ->viewport(375, 812); // iPhone viewport

    $page->assertVisible('img[alt="Libra Law Firm"]');
});
```

## Definition of Done
- [x] Logo component created with size and variant props
- [x] Logo displays correctly in navigation header
- [x] All three color variants available and working
- [x] PNG fallback works when SVG fails to load
- [x] Responsive sizing works across breakpoints
- [x] Alt text is present and translatable
- [x] Existing header.blade.php updated to use new component
- [x] Unit tests pass
- [ ] Browser tests pass (N/A - Dusk not configured)
- [x] Code formatted with Pint

## Out of Scope (Deferred)
- Footer logo placement → Story 9.7
- Email template logo → Epic 8 (Story 8.1+)
- PDF export logo → Future story

## Estimation
**Complexity:** Low | **Effort:** 2-3 hours

## QA Results

### Review Date: 2026-01-02

### Reviewed By: Quinn (Test Architect)

### Code Quality Assessment

**Overall: Excellent** - The implementation is clean, follows established patterns, and meets all acceptance criteria. The logo component is well-structured with proper props for size, variant, and text display. The SVG assets use the correct brand colors, and the PNG fallback mechanism works correctly.

**Highlights:**
- Component follows Blade component best practices with proper props definition
- Fallback sizes map correctly to story specifications (80px mobile, 120px desktop)
- All three color variants implemented with correct brand colors
- Accessible alt text using Laravel's `__()` helper for translation support
- PNG fallback via onerror attribute for email client compatibility

### Refactoring Performed

None required - implementation is clean and follows project standards.

### Compliance Check

- Coding Standards: ✓ Pint passes, proper Blade component pattern used
- Project Structure: ✓ Files placed in correct locations per source-tree.md
- Testing Strategy: ✓ 13 comprehensive unit tests covering all component props and behaviors
