/* ==========================================================================
   ADNAN KABIR — blog.css
   Loaded ONLY by blog.html. Every selector here is new or duplicated from
   about.css/case-studies.css/resources.css (never imported directly, per
   the page-isolation rule), so no other page can be affected.

   Ported from the standalone Elementor snippet at
   "WEBSITE DESIGN/FOR ELEMENTOR/BLOG/blog.html", rebuilt on this site's own
   tokens/components instead of its self-contained --d-bg/--paper palette.
   Reuses .hero, .kicker, .chip, .link-arrow, .btn, .ftabs (from
   resources.css's pattern), .briefing (main.js's newsletter handler works
   unmodified via [data-newsletter]), .finale, .footer — plus the featured
   post, the stacked sample card and the post grid, which have no
   equivalent elsewhere.
