/* Courier page: "Fahrplan" (timetable).
 *
 * Loaded after product.css. Courier is about times, so the page is a timetable. The hero is one example booking page:
 * pick a free time and see what Courier does with it. The pricing chapter is the one thing on the page that is meant to
 * be remembered: the four plans are four stops on one line, the prices are split-flap tiles like on a departure board
 * and flip when the billing period changes, and everything a plan adds is boarded at its stop.
 *
 * Palette: ink #14181a, deep teal #00485a (the site's), coral #df9784 (the site's), teal grey #83a3ac, paper #e3e8e7.
 * Coral text on paper is darkened to #9c4a37 (4.5:1). Type: Fraunces for headlines, Space Grotesk for words, IBM Plex
 * Mono for the times and the flaps, self-hosted (assets/fonts/README-eliot.txt), with the site's Helvetica and Georgia
 * as fallbacks. No request leaves rr42.de for a font.
 *
 * The billing toggle is two radio buttons and :has(), no script. The booking example is js/courier.js. Base styles are
 * the finished picture; the animations start from the unfinished one, so prefers-reduced-motion just switches them off. */
