   COA Library page (page-templates/template-coa-library.php).
   Loaded only on that page template, after main.css (shares its design
   tokens: --csc-navy, --csc-radius, etc). Kept in PepX's existing light/
   navy branding for consistency with the rest of the theme, rather than
   copying the dark theme used on the reference Amaris BioLabs page.
