/* iWhisk shared footer
 *
 * One footer across all 38 pages: the four marketing pages and the 33 guide
 * pages. Before this there were four different designs. The homepage had three
 * columns, contact/privacy/terms had a bare legal row, the guide had its own
 * three columns, and the direction study had a fourth arrangement.
 *
 * Self-contained on purpose. The marketing pages carry the sage palette
 * (--forest, --sage, --cream) and the guide carries the ink palette (--ink,
 * --canvas, --lime); neither has the other's tokens. So this file defines
 * everything it needs under its own prefix and inherits nothing.
 *
 * Every link is absolute, which is what lets one identical markup block sit at
 * three different depths: the site root, /guide/, and /guide/<section>/.
