/*
 * The public page for madarcore.app.
 *
 * Plain CSS, no build step: this page changes rarely and has no application logic, so a
 * toolchain would be pure overhead. It reuses the product's own tokens (index.css in
 * merchant-web) rather than inventing a second palette — the site and the app a merchant
 * signs into must not look like two different companies.
 *
 * Written with logical properties throughout (CLAUDE.md §14.1): this page is Arabic and
 * RTL today, and an English LTR version must not require rewriting the layout.
