/* Navy-blue brand primary for the header and navigation bar.

   Keyed to the colour *scheme* (always "default" or "slate"), not to
   `primary: custom`: the first palette entry in mkdocs.yml is the "follow the
   system" one, which carries no primary, so the statically rendered page — what
   a first-time visitor sees before any JavaScript resolves the palette — falls
   back to Material's default (indigo) for `data-md-color-primary`. Overriding by
   scheme applies the navy in that state too. This file loads after Material's
   stylesheet, so with equal specificity it wins. */
