/* The site's static pages — /guide/, /wall-clock/, /questions/ and /plans/ — share this.

   Static on purpose: no framework and no web fonts, since a page that calls a
   font CDN hands the reader's address to a third party. The colours are the
   app's own, both themes: each page follows `cul.theme.v1` when the reader
   has chosen one in the app, and is light otherwise, as the app is. */
