/**
 * Shared two-panel / full-screen shell for the 4 auth pages
 * (login, register, forgot-password, reset-password).
 *
 * Layout only — each page keeps its own inline <style> block for the card's
 * internal presentation (.auth-card-luxury, .form-group, .btn-auth, etc.)
 * and every existing id/name/class the pages' JS depends on is untouched.
 *
 * Desktop: two-panel split (visual/brand panel + form panel).
 * Mobile (<900px): visual panel hidden, form panel fills the screen edge to
 * edge — the card becomes the screen, no floating chrome.
