/* ==========================================================================
   Gut Pathways 1.7.0: bands
   Every section is a band with its own surface. The edge between two bands is
   drawn like gut tissue (a wave or a row of villi). One line language runs
   through the pages: the winding line of a fingerprint and of the gut, with
   beads. Used on About, Books, Topics and the book landing pages.
   No mono font anywhere. Without the script every finished state shows.
