/*
 * AeroBook sign-in / registration pages (0.6.60) — the dark navy "glass"
 * design from Dara's mockup (gemini-code-….html), rebuilt as plain CSS:
 * the mockup pulled Tailwind and two fonts from public CDNs, which are
 * unreliable to reach from Iran and would be a runtime dependency on
 * someone else's server for the page every user hits first. Mobile-first and
 * fully responsive (her report: the old login/registration pages were "not
 * responsive at all"): one column on phones with the form first, brand +
 * form side by side from 992px. RTL: the brand sits at the right, the form
 * at the left, on wide screens.
 *
 * The ONE stylesheet for every sign-in surface (0.6.65): the panel's sign-in and
 * registration pages (templates/components/auth-layout.php, loaded on those
 * two routes by includes/enqueue.php) and WordPress's own wp-login.php screens
 * that stay native - lost / reset password (includes/setup/login-routing.php
 * loads it there too). The font and the accent colour come from the design
 * tokens (aerobook-tokens.css, loaded first) like the rest of the panel; only
 * the dark glass palette below is this design's own.
