/*
 * Standalone "aurora" background + glass login card for csp_login.jsp only.
 * Loaded exclusively by that page, so every rule here (including the
 * .header-main-banner / .main-sidebar overrides near the bottom, which
 * reach outside .vt-login-page) is scoped in practice by inclusion, not by
 * selector - this file is never linked from any other page.
 *
 * Palette/animations are adapted from https://ventura.fscx.my/ (the brand's
 * own "coming soon" splash) so the login page reads as the same product,
 * retinted so the venturaV1 app theme's accent (a warm tan/gold, #E7B789
 * base - see --vt-accent-* in theme.css) leads instead of the splash page's
 * blue or this file's own earlier purple.
