PR Summary

Low Risk
Single CSS selector change in a presentational component with no auth, data, or API impact.

Overview
BaseCodeBox styling now targets code anywhere under .content instead of only a direct child of the pre, so typography and line-number layout still apply when something sits between the pre and code (e.g. SSR/hydration or richer markup).

Shipped as a patch for @node-core/ui-components via changeset.

Incomplete nested code selector update

Medium Severity

The PR widens .content code styles to descendants so a wrapper between pre and code still matches, but the no-line-numbers rule still uses a direct-child > code selector. With that wrapper, short blocks keep line-number padding and counters even when no-line-numbers is set.
