 * Book2Brain — over the template.

 * The template was built for a pink brand on a photographic hero: the header
 * is transparent with white links, which on a white page is invisible, and
 * every button is a two-colour gradient that turned muddy once the pink
 * became brass. This file fixes those rather than editing the template.
