Fixes the ChatGPT white message bug that appears in dark mode when user messages have a white background instead of matching the dark theme.

  • ✅ Injects a CSS override to restore background color
  • ✅ Lightweight and non-intrusive
  • ✅ Uses Tampermonkey, no permissions needed

Bug example:

Technical details:

  • Applies background-color: var(--main-surface-secondary)
  • Injected after 500ms delay to ensure DOM readiness

Install with Tampermonkey. Customize the CSS if desired.
