Function computeArticleHeadMetadata

computeArticleHeadMetadata(input: ArticleHeadMetadataInput): ArticleHeadMetadata
Compute the canonical <head> metadata for an article.md exactly the way the article renderer does. Used by:
- ./article.ts | renderArticleHtml during real article generation
- ../test-article-headers.ts | test-article-headers CLI for auditing the shipped corpus
The two callers MUST share this function so the audit report can never drift from what is actually rendered into HTML.
Parameters
- input: ArticleHeadMetadataInput
Returns ArticleHeadMetadata
