🎨 Add custom favicon for better branding

[0GiS0]

🔍 Issue

The application currently does not have a custom favicon. When users open the app in their browser, they see either:

• The default browser icon
• A missing image placeholder
• The generic HTML5 icon

💡 Proposed Solution

Add a custom favicon that represents the OAuth 2.0 Device Code Flow concept. Suggestions:

1. Create a favicon that includes:

   • A lock icon 🔒 (representing security/authentication)
   • A device icon 📱 (representing device code flow)
   • Azure/Microsoft colors to align with the Azure AD theme

2. Generate multiple sizes for different platforms:

   • favicon.ico (16x16, 32x32, 48x48)
   • favicon-16x16.png
   • favicon-32x32.png
   • apple-touch-icon.png (180x180 for iOS)
   • android-chrome-192x192.png
   • android-chrome-512x512.png

3. Add the favicon references to views/partials/header.ejs:

<link rel="icon" type="image/x-icon" href="/favicon.ico">
<link rel="icon" type="image/png" sizes="16x16" href="/favicon-16x16.png">
<link rel="icon" type="image/png" sizes="32x32" href="/favicon-32x32.png">
<link rel="apple-touch-icon" sizes="180x180" href="/apple-touch-icon.png">

4. Place favicon files in the public/ directory

🎯 Benefits

• Professional appearance - Makes the demo look polished and complete

• Branding - Reinforces the purpose of the application
• Bookmarking - Provides a recognizable icon when users bookmark the page
