/* mdbook-og-cards: Open Graph preview card styles.
   Designed to work with mdBook's built-in themes (light, rust, coal,
   navy, ayu) using their CSS custom properties, so cards automatically
   match whichever theme the reader has selected (including dark mode).

   Note: the card markup (src/renderer.rs) intentionally uses only
   inline/phrasing HTML tags (a, span, strong, small, img) because it is
   frequently spliced into the middle of a Markdown paragraph, which gets
   wrapped in a <p> by mdBook. A block-level tag (div, p, ul, ...) in that
   position would cause the HTML5 parser to auto-close the surrounding
   <p> and mangle the DOM. All layout below is done with `display`
   overrides on those inline tags rather than relying on block-level
   elements. */
