favicon.svg is a violet book with gold corners and clasp and a four-pointed star
in a ring, replacing the indigo book with a spark. It is rendered to 192 and 512
PNG app icons and a 180 touch icon on the page surface.
manifest.json lists those icons instead of a favicon.ico that never existed. It
describes the product as the README does, and takes its colours from the design
system's page surface. index.html's theme-color follows.
