/* Curl
 *
 * A price comparison desk. It answers one question — where are we being
 * undercut — and everything on screen either answers it or gets out of the
 * way. Prices are numbers; numbers get tabular figures and right alignment,
 * and the difference between our price and the best competitor is the single
 * most important thing on any page, so it is the thing with colour.
 *
 * The old version was three Bootstrap buttons and a table with inline styles.
 * This one has no framework: one file, no CDN, works when the CDN does not.
