   File: assets/css/guides.css
   Purpose: Guides hub, single-guide e-reader, and sources page for
            columbusconstructioncost.com. Reads the --ccc-* tokens
            declared in assets/css/site.css :root; loaded per-view by
            guides/index.php, guides/show.php, guides/sources.php, and
            (for the .guide-router-tag pill only) public/landing.php.
            Mechanism ported from columbusremodelcost.com's guides.css
            2026-09-26 and re-themed to this site's palette and section
            conventions — the page hero reuses the existing
            .dark-band/.blog-hero photo band from assets/css/blog.css
            rather than introducing a second hero pattern.
