/*
 * The sign-up page. `TODO.md` §51.
 *
 * Standalone, like the how-it-works page beside it, and for the same reason: this folder is
 * copied to the VPS and served as plain files, so it must not need a bundler, a session or
 * anything from the app. The two fonts are borrowed from `../how-it-works/fonts/`, which is
 * deployed to the same document root - one copy, not two.
 *
 * The art direction is the app's: a dark room, one lit rectangle, hairlines instead of cards,
 * and the brand yellow used only for the single action on the page.
