Pull request overview
This PR adjusts the default theme’s CodeBlock styling so Shiki-rendered code blocks keep their background color visible across the full horizontally scrollable width (preventing the “white gap” when long lines overflow).
Changes:
- Make the
<pre>element expand to the scrollable content width by usingwidth: fit-contentwithmin-width: 100%. - Preserve existing behavior where wrapped code still occupies at least the container width.

Summary
This PR fixes code block backgrounds becoming white when horizontally scrolling overflow with a dark Shiki theme.
Before, the
<pre>element stayed at the visible container width while the nested<code>element expanded to the content width, exposing the surrounding light background. After, the<pre>element covers the full scrollable width while preserving wrapped code behavior.Related Issue
