   BREADCRUMB

   Sao Viet theme addition (not part of /reference's own styles.css):
   plain-background breadcrumb styling for pages with no dark banner
   image behind it (single-job.php, single-training.php, single.php).
   Banner pages use the separate .breadcrumb-custom variant (white
   text over a dark image, styled in each page's own CSS file) —
   :not(.breadcrumb-custom) keeps this rule from touching those.
   Without this, the links fall back to the browser's default blue/
   underline instead of the site's own palette.

   /reference (which loads every CSS file on every page), this theme
   enqueues page CSS conditionally, so doi-tac/lien-he never loaded
   about.css and rendered the CTA band unstyled. Living in styles.css
   (loaded on every page) fixes that for any page that uses the
   shared template-part, present or future. */
