/*
 * Paytrack product site (kirbyservice.net): Register's component (round 3,
 * plan.md). A tent card with the real QR stands on a soft counter, Ai beside
 * it; a floating phone scans the code, fills the check-in form and hands the
 * job card to the board. Markup in obj/part_register.php, steps and typing in
 * js/parts/register.js, the runner in js/parts/part.js. Keep this file ASCII.
 *
 * The whole scene is sized in em: .pt-part-stage sets the unit from the
 * column's width (container units), so every part keeps its place at every
 * size and no text drops below 10px (the smallest text is .84em of at least
 * 12.2px). Two compositions: wide (desktop and tablet, 36 x 20 em) and narrow
 * (phones, 26 x 20.4 em). Motion is transform and opacity only; the steps are
 * the pt-sN classes and data-step (part.js), the beats inside a step are the
 * rb-* classes (register.js). Elements marked .rg-mv take the quick and snap
 * modes at the end of this file.
