📝 Walkthrough

Walkthrough

This pull request updates documentation in the i18n integration guide to reflect how slug computation handles array route parameters. The change shows that when route.params.slug is an array, the segments are joined with '/' before applying withLeadingSlash, whereas previously the slug was always converted directly from String(route.params.slug). This affects the resulting slug value used for page cache keys and content queries.
