/*
 * The gradient is the logo's, stop for stop, so the mark and the site cannot
 * drift apart:
 *
 *   #053D94  deep blue      gradient start
 *   #2B2FB2  indigo         gradient middle
 *   #9F1BE8  violet         gradient end
 *   #2F1366  dark purple    the wordmark, and this site's near-black
 *
 * The working accent is #1737A2, which sits between the gradient's first two
 * stops rather than on one of them. Links, borders and small type all take it,
 * and a shade deeper than the indigo suits that: it reads 10:1 on white
 * against the indigo's 9.8, and it stays clearly a blue where the indigo was
 * beginning to look violet at small sizes.
 *
 * Violet only manages about 5:1 on white, so it stays in the gradient and in
 * large elements, never behind body text.
