 * The site footer.
 *
 * Light, like the French one. The previous footer was a dark navy band, which
 * on an otherwise white page is the single loudest thing on the site — and the
 * loudest thing on a page should not be the legal small print.
 *
 * Rhythm: a call to action on its own line, then the columns, then the legal
 * matter separated by a rule and set smaller. Three tiers, each quieter than
 * the one above it.
