/*
 * duetrack.co — the public site.
 *
 * Layout follows the attached template's rhythm: a full-bleed hero, alternating
 * white and tinted sections at generous vertical padding, a promo trio, a
 * screenshots strip and a pricing table. The palette is DueTrack's own rather
 * than the template's blue and green — the mark is a purple squircle with gold
 * sand in it, and a site in someone else's colours would not look like the app
 * it is selling.
 *
 * Hand-written CSS, no framework: this is three static pages that must load
 * instantly on a phone, and shipping a build system to style them would be the
 * expensive way to get a worse result.
