🔧 Build Fix:

The PageTOC and PageTOCItems components have been removed in fumadocs-ui v16.2.3. The code imports these non-existent components from fumadocs-ui/layouts/docs/page, causing Turbopack compilation to fail. Additionally, the generatePageMetadata and generateStaticPageParams functions are missing from the docs-page.tsx wrapper component.

Fumadocs UI v16.2.3 Breaking Change: Missing Component Exports

What fails: Turbopack compilation fails due to missing exports from fumadocs-ui v16.2.3 after dependency upgrade from v16.0.10 to v16.2.3.

How to reproduce:

cd apps/website && npm run build

Result:

Export PageTOC doesn't exist in target module
Error: Turbopack build failed with 6 errors:
./apps/website/components/geistdocs/toc.tsx:3:1
Export PageTOC doesn't exist in target module
./apps/website/components/geistdocs/toc.tsx:3:1
Export PageTOCItems doesn't exist in target module

./app/docs/[[...slug]]/page.tsx:5:1
Export generatePageMetadata doesn't exist in target module
Export generateStaticPageParams doesn't exist in target module

Root cause: The fumadocs-ui library v16.2.3 removed the PageTOC and PageTOCItems components from fumadocs-ui/layouts/docs/page. These were refactored and the TOC components are now available from fumadocs-ui/components/toc/clerk. Additionally, the metadata generation functions were not exported from the local docs-page.tsx wrapper component.

Fix:

1. Updated apps/website/components/geistdocs/toc.tsx to import TOCItems from fumadocs-ui/components/toc/clerk instead of the removed PageTOC and PageTOCItems
2. Replaced the PageTOC wrapper component with a standard aside element to maintain the same DOM structure
3. Removed the unused variant="clerk" prop from PageTOCItems (now just TOCItems)
4. Added missing generateStaticPageParams and generatePageMetadata exports to apps/website/components/geistdocs/docs-page.tsx that are required by the page route handler
