/* =====================================================================
 * EASRMS - Login Page (v3 - 2026)
 *
 * Goals:
 *  - Mobile-first, FULLY responsive (looks great 320 -> 4K)
 *  - Light, multi-color pastels - not heavy
 *  - NOT boxy: rounded, soft, single connected layout
 *  - Desktop: form on the LEFT, features list on the RIGHT, separated by a
 *    thin vertical line (no second card / no second box)
 *  - Mobile: ONLY the form. Decorations and feature list are hidden so the
 *    user does NOT need to scroll to log in.
 *  - Smooth, calm animations (no spinning rings, no busy clutter)
 *
 * Class prefix: lx-  ("login experience")
