Fenced code blocks on /changelog rendered on a single line. The main code rule sets white-space: nowrap for inline code, and it also applied to <pre><code>, so the lines in the v2.2.0 diff block were joined and the line widened the page.

This change adds two rules:

• main pre code { white-space: pre; } keeps the line breaks.
• main pre { overflow-x: auto; margin: 0 0 12px; } scrolls long lines inside the block instead of the page and matches paragraph spacing.

No syntax highlighting is added.

Verification: I rendered the current CHANGELOG.md through the worker's handle() at 1280px and 390px in dark mode. The diff block shows four lines, and the <pre> scroll width equals its client width at both sizes. bun test and bun typecheck pass in services/changelog.

The fix looks correct. The new main pre code { white-space: pre; } rule is more specific than main code { white-space: nowrap; }, so code blocks keep their line breaks and inline code still doesn't wrap. overflow-x: auto keeps long lines scrolling inside the block, and the 12px bottom margin matches .markdown p.

I rendered the current CHANGELOG.md through handle() and confirmed the diff block comes out as <pre><code> with its newlines and the new rules are in the page CSS. I couldn't check the page in a browser here; there is no browser in my sandbox. bun test passes and tsc --noEmit passes.

The public API is unchanged; only the changelog page's CSS changes.

I have no concerns.
