/**
 * ClassFlow LMS — Unique login screen.
 *
 * A full-screen, split-panel sign-in experience shown whenever a logged-out
 * visitor lands on a teacher/student dashboard (and via the [classflow_login]
 * shortcode). Every selector is scoped under `.classflow-login` so the active
 * theme cannot override it and the styles never leak out to the rest of the
 * site. Tokens are redeclared here (rather than inherited from the dashboard)
 * so the screen is fully self-contained.
