/* ============================================================
   oSTEM @ UMich - style.css
   Palette: U-M blue (#00274C) + maize (#FFCB05) on warm paper.
   Signature: a thin 6-stripe "pride rule" under the header and
   above the footer, echoed as heading underlines.

   ACCESSIBILITY NOTES (please keep these rules intact):
   • Maize text is NEVER placed on white - it fails contrast.
     Maize is used only as a background (with blue text) or on blue.
   • All interactive elements have a visible :focus-visible style.
   • Animations are wrapped in prefers-reduced-motion checks.
