/* ============================================================================
   The blog's own layer.

   site.css is loaded first and carries everything shared — the tokens, the
   faces, .wrap, .mono, .logo, .cbtn, the cursor, the scrollbar, the cookie
   notice. This file styles only what exists nowhere else: the article page
   and the index. Everything here is prefixed bl- so nothing can collide with
   the landing page's classes.

   The entrance is CSS-only. These pages deliberately do not load app.js, so
   the section-entrance engine is not here to call on — a keyframe on load
   reads as considered and costs no script.
