X Background Customizer

Brings back the navy-blue "Dim" background on X (formerly Twitter) dark mode.

X removed the Dim theme option, leaving only pure black. This extension restores the familiar navy (#15202b) background — including borders, hover states, and UI elements — for a more comfortable browsing experience.

Features:
- One-click ON/OFF toggle
- Instant activation, no page reload needed
- Zero data collection — fully open source
- Works on both x.com and twitter.com

How to use:
1. Install from the Chrome Web Store
2. Open X (x.com) and enable dark mode
3. Click the extension icon in the toolbar, turn it ON, then reload the X page
