Previous attempt was being overridden by Tailwind prose/prose-invert
CSS variables. This fix:
- Overrides --tw-prose-pre-bg and --tw-prose-invert-pre-bg CSS variables
on .paperclip-markdown to force dark background in both modes
- Uses .paperclip-markdown pre with \!important for bulletproof overrides
- Removes conflicting prose-pre: utility classes from MarkdownBody
- Adds explicit pre code reset (inherit color/size, no background)
- Verified visually with Playwright at desktop and mobile viewports
