/* ==========================================================================
   Secretary42 — site chrome for the standalone secretary42.de build
   --------------------------------------------------------------------------
   website/secretary42/secretary42.css scopes everything under `.s42-page`
   because it has to coexist with a WordPress theme. secretary42.de has no
   theme, so this file supplies what the theme used to: the page background,
   the site header/nav and the footer.

   The palette is duplicated here (rather than imported) because the product
   CSS defines its custom properties on `.s42-page`, and the chrome lives
   outside that element. Keep the two in sync if the brand colours change.

   The nav toggle is CSS-only. A previous build of this site used a Bootstrap
   hamburger whose JavaScript never loaded, leaving the mobile menu dead; with
   no script involved that cannot happen again.
