/* =============================================================================
   single-publication.css
   Dark "Text A" editorial skin for the single Publication template
   (single-publication.php, wrapped in .publication-single).

   Enqueued only on is_singular('publication') in functions.php, AFTER main.css
   (dependency: saab-main-css), so the --brand-* custom properties resolve from
   main.css's :root.

   Scope: .publication-single. Mirrors the structure of single-tw.css.
   Palette: cream = var(--brand-cream, #FEFEFE). Never use --white (undefined).
