   ----------------------------------------------------------------------------
   Scoped entirely to .blog-article-content, so nothing outside a single post
   can be affected. Loaded AFTER main.css, so equal-specificity rules win.

   Colours use the site's own tokens (--at-neutral-*, --at-theme-primary).
   [data-bs-theme=dark] remaps those tokens upstream, so dark mode follows
   automatically and needs no parallel colour block.

   Fixes measured on the live page before this file existed:
     body line-height 1.2  -> 1.75      (was unreadably tight)
     117 characters/line   -> ~72       (was far past the 60-80 comfort range)
     h2 72px / h3 64px     -> 34 / 26   (display sizes leaking into body copy)
     heading margin-top 0  -> real space before each section
     li margin-bottom 0    -> list items no longer collide
     body weight 500       -> 400       (500 is a heading weight)
     body colour #585959   -> neutral-900 (contrast on white was marginal)
