/* Local CSS variables.
   `--jinan-teal`, `--jinan-gold`, `--jinan-charcoal` and `--white` are
   already defined globally by theme-variables.css. Re-declaring them as
   `--jinan-teal: var(--jinan-teal)` here created a circular reference
   that resolved to the initial value (empty) on this file's :root, and
   that "shadow" then propagated to descendants — killing the
   .major-hero linear-gradient (which depends on var(--jinan-teal) +
   var(--jinan-teal-dark)) and leaving the hero unstyled. Only declare
   variables that don't already exist at the global level. */
