/*
 * The VeriPlus loader: the mark assembling itself. The arcs turn in, the
 * check grows out of its vertex, and the plus pops last.
 *
 * Transform and opacity only. Dash-offset drawing rendered wedge-shaped
 * slivers in Chrome on the parent site, so it is not used.
 *
 * One stylesheet, two users: the preloader inside #root in index.html (shown
 * before the JavaScript arrives, replaced the moment React mounts), and the
 * <Loader /> component (src/components/Loader.tsx) that React shows while a
 * page's code loads. It is a plain file in public/ and linked from index.html
 * because the CSP allows no inline styles.
