/* ---------------------------------------------------------------------------
   blog-article.css -- presentation for long-form blog posts.

   Mezzanine sanitises rich text with bleach (RICHTEXT_FILTER_LEVEL = high), which
   strips <svg>, and keeps only a short whitelist of inline styles. So every visual
   element an article needs has to be reachable through a class name on a whitelisted
   tag. That is what this file provides: post bodies stay plain semantic HTML and
   survive a round-trip through the admin editor untouched.

   Scoped to .rs-blog-details .bs-desc so nothing here leaks into the rest of the site.
   Palette follows the site: #607d8b brand, #21aa50 green, #212121 ink, #666 body.
