/*
 * TUI Harriet - Login Page Branding
 * Matches mockup: white background, dark glassmorphism box, TUI styling
 * SAFE: No visibility:hidden, no page replacement
 * 
 * NOTE: This CSS is loaded on ALL pages (via base.html), but the rules
 * only target login page elements (.login-page, .portico-header, etc.)
 * so logged-in pages are not affected.
