/* Login page for the new student experience (templates/login/lms_login.html).
 *
 * Layered over frappe's login.bundle.css: frappe's classes keep their markup
 * and behaviour, this file only re-lays them out as a split screen and applies
 * the student palette. The values mirror the SPA's --sx-* tokens
 * (frontend/src/styles/student-theme.css); the SPA stylesheet is not loaded on
 * this server-rendered page, so they are repeated here.
 *
 * The form column takes its cues from the RMU auth screens: the logo sits at
 * the top of the form, labels are small and uppercase, fields are filled and
 * rounded, and the primary action is a full-width pill.
