/* ==========================================================================
   PKOUG — blog index and article.
   Loaded after pkoug-tokens.css and pkoug-components.css, and built only
   from their tokens, so both themes and the 360 px width come for free.

   Replaced assets/blog.css and assets/blog-premium.js, both since deleted.
   The reveal
   animations those provided are gone on purpose: they needed JavaScript to
   make the page visible at all, which meant no article rendered without it.
