… the Next.js docs build to fail with "Module not found".
This commit fixes the issue reported at apps/docs/content/docs/reference/scan.mdx:9
**Bug:** The file `apps/docs/content/docs/reference/scan.mdx` contains `import { Callout } from '#/components/callout';` on line 9. This module path `#/components/callout` does not resolve to any file — there is no `#` path alias configured in tsconfig.json or package.json imports, and no `callout.tsx` exists at that path. The `Callout` component is provided globally through `apps/docs/components/geistdocs/mdx-components.tsx`, and all 6 other MDX files in the same directory use `<Callout>` without any import.
This causes the Next.js docs build to fail with `Module not found: Can't resolve '#/components/callout'`.
**Fix:** Remove the broken `import { Callout } from '#/components/callout';` line from `scan.mdx`. The `<Callout>` component usage remains and will work correctly via the global MDX component injection, matching the pattern used by every other file in the directory.
