The blog automatically adapts to your browser's color scheme preference. Dark mode is implemented using CSS media queries:

@media (prefers-color-scheme: dark) {
  /* Dark mode styles */
}

To test dark mode:

• macOS: System Preferences → General → Appearance → Dark
• Windows 10/11: Settings → Personalization → Colors → Choose your color → Dark
• Chrome/Edge: DevTools → Command Menu (Ctrl+Shift+P) → "Rendering" → Emulate CSS media feature prefers-color-scheme
