The new H1 duplicates the metadata.description and doesn’t match metadata.title, which is inconsistent with the other blog MDX posts where the H1 mirrors metadata.title. This will make the on-page heading differ from the post title shown in listings/SEO metadata. Consider changing the H1 to the metadata.title value and keeping this longer sentence only in metadata.description (and without a trailing period, to match other H1s).
