/* The quote instrument, in its three mounts.

 *   hero     /             location, dates, a live total, a link that carries it
 *   full     /preventivo/  ribbon, fleet picker, extras, sticky summary
 *   fleet    /flotta/      six uniform cards, each priced for the chosen dates
 *
 * The summary used to be a bar fixed to the bottom of the window. It is now a
 * column that sticks below the header instead: a fixed bar can sit on top of the
 * control a keyboard user has just moved focus into, which WCAG 2.2 rules out.
 *
 * Everything measured is monospaced — a rate should read as though it came off
 * the desk's terminal.
