/* auth-design.css — DashProyectos auth (login + signup + verify)
 *
 * Implementación del rediseño de Claude Design (DashProyectos Auth.html).
 * Filosofía: "Donde todo se conecta." — visualizado en 5 capas:
 *   1) Glow ambient (CSS)
 *   2) Particle network con hubs/team/data + pulses + ripples + magnet (canvas)
 *   3) Card glassmorphic con backdrop-blur + edge-glow para conector
 *   4) Toggles internos = cross-fade limpio (mismo card)
 *   5) Card-to-card = slide-out + connector bezier (entre páginas reales se simula)
 *
 * Las páginas auth NO cargan components.css ni variables.css del dashboard
 * para evitar choques de selectores (.card, .input, .btn, etc.) — todos los
 * tokens que necesitamos están en :root acá.
