/* ============================================================
   File: assets/css/blog.css
   Purpose: Blog + glossary styling for columbusconstructioncost.com,
            written in the site's own design language (site.css tokens:
            --ccc-* palette, Inter, 1100px shell). Replaces the funnel
            template's public.css, which did not survive the conversion.
   Loaded:  per-view via the layout's "styles" section
            (blog.php, blog_post.php, glossary.php, glossary_term.php,
            guides/*). The .dark-band/.blog-hero photo band here is the
            shared page-hero mechanism those views reuse.
   Author:  iSpec LLC
   Created: 2026-08-06
   History: 2026-08-14 — .glossary-term-source "See also" link row
            (roof/kitchen/bath glossary parity)
   Last Modified: 2026-09-26 — .cta-band h3 rule became .cta-band h2 (the
            glossary index's closing band is a page-level section); the
            per-term glossary pages' own rules live in
            assets/css/glossary.css, not here
