Enable post preview for a less dull experience
This will be used, along with other Open Graph (OG) metadata, for rich preview cards on sites like Discord, Twitter/X, Slack, LinkedIn, etc. - Title (og:title) - Description (og:description) - Preview image (og:image) - Site name (og:site_name) - URL (og:url) To prevent the card's 'image:' from the front matter to be used by Chirpy as a "hero image" in the post, we override the default post layout and add a per-post image setting 'show_in_post: false'.
