   Booking pages — /book/ and a customer's own booking.

   Loaded only on those pages, after styles.css, and written entirely in that
   file's tokens: a re-skinned site re-skins its booking pages with no edit
   here. Nothing in this file names a colour or a font.

   Every control is a real link or a real button, 44px or taller, so the
   whole thing works on a phone with JavaScript off.
