data-pagefind-filter attribute on the enclosing
element for PageFind faceted search.

<p>CONTROLLING WHICH FIELDS ARE PUBLISHED (allowed_meta_fields)</p>
By default all front matter keys are emitted as
<meta>
<p>elements. To restrict which keys are published, set
allowed_meta_fields in page.yaml:</p>
<pre><code>allowed_meta_fields:
- title
- author
- description
- keywords
- series
- seriesNumber</code></pre>
<p>When this list is set, only the listed keys appear in generated HTML.
Internal workflow fields (build flags, notes) are silently omitted.</p>
