Added CSS color-scheme to app/globals.css to improve the native UI styling of scrollbars and other browser elements when switching between light and dark modes. I also ensured no dev artifacts were committed.

Summary by CodeRabbit

  • Style
    • Updated color scheme declarations to provide better browser hints for light and dark mode rendering, improving visual consistency across different system preferences.

This commit adds `color-scheme: light;` to the `:root` selector and `color-scheme: dark;` to the `.dark` selector in `app/globals.css`. This ensures that the browser correctly styles native default UI elements, like scrollbars, context menus, and inputs, to match the website's active theme.

📝 Walkthrough

Walkthrough

Added CSS color-scheme declarations to the global stylesheet. The :root selector now explicitly declares light color-scheme, while the .dark class declares dark color-scheme, providing browser hints for preferred color rendering.

200-223: Consider making custom scrollbar styles theme-aware.

The custom WebKit scrollbar styles use hardcoded dark colors (#161022, #2e2839). With the new color-scheme declarations, native scrollbars in Firefox will now adapt to light/dark mode, but WebKit browsers will show dark scrollbars in both themes.

This is a pre-existing issue outside the scope of this PR, but you may want to address it for visual consistency.

♻️ Example: Theme-aware scrollbar styles
 /* Scrollbar Styles */
+:root {
+  --scrollbar-track: `#e5e5e5`;
+  --scrollbar-thumb: `#c1c1c1`;
+  --scrollbar-thumb-hover: `#6c2bee`;
+}
+
+.dark {
+  --scrollbar-track: `#161022`;
+  --scrollbar-thumb: `#2e2839`;
+  --scrollbar-thumb-hover: `#6c2bee`;
+}
+
 ::-webkit-scrollbar {
   width: 8px;
   height: 8px;
   transition: width 0.2s ease;
 }

 ::-webkit-scrollbar:hover {
   width: 10px;
 }

 ::-webkit-scrollbar-track {
-  background: `#161022`;
+  background: var(--scrollbar-track);
   border-radius: 4px;
 }

 ::-webkit-scrollbar-thumb {
-  background: `#2e2839`;
+  background: var(--scrollbar-thumb);
   border-radius: 4px;
   transition: background 0.2s ease;
 }

 ::-webkit-scrollbar-thumb:hover {
-  background: `#6c2bee`;
+  background: var(--scrollbar-thumb-hover);
 }
