   The palette is the app's own, read straight out of
   Nombook/Resources/Assets.xcassets/Colors. If a colour changes there,
   change it here and nowhere else: these three pages share this file so
   the site can't drift into three slightly different creams.

   /recipe/index.html deliberately does NOT use this file. That page is the
   shared-recipe landing, it redirects to the App Store within two seconds,
   and it must keep working if anything else on this domain breaks — so it
   stays a single self-contained file with its own inline copy of the tokens. */
