/* ==========================================================================
   AMS v89.56 fix 65 - the Digital Library gets the AMS visual refresh
   ("Theme A": navy and gold), the same stylesheet rules as AMS
   assets/css/theme.css (fix 64) plus the few Library-only surfaces below.
   Loaded by includes/header.php AFTER ams-style.css and style.css. Colours,
   type and surfaces only - no markup, layout, text or position change; delete
   this file and every page is exactly as it was. Fonts: Inter Display,
   self-hosted Latin subsets in assets/fonts (SIL OFL 1.1, assets/fonts/OFL.txt).
