/* Footer, light mode only: light ivory bar with charcoal text.
   Material colors footer text via these variables (default: white at various
   opacities), so overriding the variables recolors the copyright line, the
   prev/next hints, and the links together. Setting `color` on the containers
   alone does NOT work -- `.md-copyright` and `.md-copyright__highlight` carry
   their own explicit color rules that beat inherited values.

   Dark mode is deliberately left alone: Material's stock footer is already
   near-black with white text, which is what we want against the slate scheme. */

   Kit newsletter signup (docs/overrides/partials/newsletters.html)

   Replaces the ~590 lines of inline CSS from Kit's HTML embed. Uses Material's
   real theme variables so it tracks the palette in both schemes:
     --md-default-bg-color / --md-default-fg-color  page surface + text
     --md-accent-fg-color                           the "deep orange" accent
     --md-primary-fg-color                          the "teal" primary
   (Note: --md-card-background-color, --md-text-color and --md-accent-color are
   NOT Material variables -- an invalid var() makes the browser drop the whole
   declaration, so those silently do nothing.)
