/* Ad slots — inline promo banner + the media|demo modal.
   Uses the same theme tokens as blog.css/post.css (paper/ink palette,
   spacing/radius scale, [data-theme="dark"] overrides) so the palette
   matches the post — but the surface, shadow, and "Ad ·" label are
   deliberately distinct from a regular content card. It should read as
   inserted advertising at a glance, not as another section of the article. */
