   Styling for rendered Markdown (app/models/blog/post.rb → kramdown).

   Plain CSS rather than Tailwind utilities, for two reasons. kramdown emits
   bare HTML with no classes, so utilities would mean a `prose` plugin or
   post-processing the output; and a Tailwind class that has never appeared in
   this codebase does not exist until the CSS is rebuilt, which fails silently
   (see CLAUDE.md). Everything here is scoped under .blog-prose / .blog-video,
   so none of it can leak onto the canvas or the marketing pages.
