/* ============================================================
 * MODAL DE FORMULARIO — Ajustes y el primer paso del onboarding.
 * Vivía dentro de perfil.html, pero el wizard del shell necesita el mismo
 * chasis: cabecera con miga, nav numerada, paneles y pie con la acción.
 * Quien lo use solo pone el marcado; el aspecto sale de aquí.
 * Casa (26-09-2026): sin hairlines entre cabecera, nav, filas y pie (los
 * separa el espacio), campos en línea, idiomas como chips con la bandera
 * en el hexágono, ciclo como segmento, título elegido con luz.
