━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Total Icon-Only Buttons Found: 15+
Properly Labeled: 14/15 (93%)
Missing Labels: 1 location (image gallery thumbnails)

✅ PROPERLY LABELED:

  • Theme toggle button (1 instance)
    └─ File: (dashboard) layout, line 150
    └─ Example: aria-label={theme === 'light' ? t('dashboard.darkMode') : ...}
  
  • Language switcher (1 instance)
    └─ File: components/ui/language-switcher.tsx, line 29
    └─ Example: aria-label={`${t('label')}: ${t(locale)} → ${t(nextLocale)}`}
  
  • Image gallery navigation (2 instances)
    └─ File: components/listings/image-gallery.tsx, lines 47, 54

     └─ File: apps/web/components/listings/image-gallery.tsx:69-84
     └─ Issue: No aria-label on <button> elements
     └─ Impact: Screen reader only announces "button" without context
     └─ Fix: Add aria-label={`Select image ${index + 1}`}
     └─ Priority: CRITICAL


━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
3️⃣ FORM INPUTS WITHOUT LABELS
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Total Form Inputs: 25+
Properly Labeled: 24/25 (96%)
Missing Visible Labels: 1 input

✅ PROPERLY LABELED FORMS:
  ✅ Login Form (2 inputs)
     File: apps/web/app/[locale]/(auth)/login/page.tsx
     Pattern: <Label htmlFor="phone"> + <Input id="phone">
     + Includes aria-describedby for errors

🟡 NEEDS IMPROVEMENT:
  ⚠️ Landing Page Search Input
     File: apps/web/app/[locale]/(public)/page.tsx:87-92
     Current: Only has aria-label, no visible label
     Issue: Visual users don't see field purpose
     Fix: Add <label htmlFor="search-input" className="sr-only">


━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
4️⃣ SKIP-TO-CONTENT LINK
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Status: ✅ PROPERLY IMPLEMENTED

Location: apps/web/app/[locale]/layout.tsx:105-110

    href="#main-content"
    className="fixed left-2 top-2 z-[100] -translate-y-16 rounded-md..."
  >
    {t('skipToContent')}
  </a>

Features:

  ✅ Proper link semantics using <a> tag

Target Element Found:
  Location: apps/web/app/[locale]/(public)/layout.tsx:148
  Code: <main id="main-content" role="main">{children}</main>

Additional Main Elements:
  ✅ apps/web/app/[locale]/(public)/layout.tsx:148

5️⃣ INTERACTIVE ELEMENTS WITHOUT ACCESSIBLE NAMES
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Total Interactive Elements Reviewed: 50+

✅ WELL-NAMED ELEMENTS:
  ✅ All Primary Buttons: Have visible text
  ✅ All Navigation Links: Have visible text
  ✅ Most Icon-Only Buttons: Have aria-labels
  ✅ All Form Controls: Have labels or aria-labels
  ✅ Cards: Have article labels (property cards)

🔴 NEEDING ATTENTION:
  
  ❌ CRITICAL: Image Gallery Thumbnail Buttons
     File: apps/web/components/listings/image-gallery.tsx:69-84
     Issue: No aria-label on thumbnail selection buttons
     Impact: Screen readers say "button" with no context
     Fix: Add aria-label={`Select image ${index + 1}`}
  
  ⚠️ MINOR: Navigation Links (redundant labels)
     File: apps/web/app/[locale]/(dashboard)/layout.tsx:125
     Issue: aria-label on links when text is visible
     Recommendation: Remove aria-label (visible text is better)


━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
7️⃣ COLOR CONTRAST & THEME SYSTEM
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Status: ⚠️ NEEDS VERIFICATION

Color System Implementation:
  File: apps/web/tailwind.config.ts
  Format: HSL CSS Variables
  Theme: Light/Dark mode support

CSS Variables Defined:
  --border, --input, --ring
  --background, --foreground
  --primary, --primary-foreground
  --secondary, --secondary-foreground
  --destructive, --destructive-foreground

  --accent, --accent-foreground
  --card, --card-foreground

Theme Implementation:
  File: apps/web/components/providers/theme-provider.tsx

  ❓ Primary text on white background (4.5:1 minimum)
  ❓ Primary text on muted background (4.5:1 minimum)
