/* ============================================================================
   Blog article (case study) — single post layout. Requires blog.css.
   ============================================================================

   Ported from zipify-refresh's `assets/redesign/css/blog-article.css`.

   Removed on the way across, all of it dead in this theme:
     * the base reset (`*`, `html`, `body`) — theme.css owns those, and the
       article's page ground lives on `body.zp-blog` in blog.css.
     * `.footer-zone` / `.footer-brand` / `.footer-col`. The source shipped its
       own in-article footer block; `single.php` never rendered it even there,
       and this theme renders `.zp-footer` on every surface.
     * the duplicate `.input` definition at the foot of the source file, which
       restated components.css verbatim. blog.css carries the single copy.

   Changed on the way across: the sticky rail and the heading scroll-margins
   were hardcoded to 88px, an offset derived from the old 70px nav. Both now key
   off `--zp-header-h` so they track this theme's header.

   Note that `.apps-strip`, `.app-tile`, `.founder-quote`, `.lead-cover` and
   `.news-form` are also defined in blog-index.css with different values. That
   is inherited from the source and safe: the two sheets are enqueued on
   mutually exclusive surfaces (`is_singular('post')` vs. everything else), so
   they never meet in one cascade.
