/*
 * 3r_projects — hoja de estilos principal.
 * Base visual de hwdpos (barra lateral blanca, contenido gris claro, tarjetas con borde fino) con el
 * azul de la marca 3R (#0d6efd) y criterios de las Human Interface Guidelines de Macintosh (1992):
 *  · Estabilidad percibida: la barra lateral y la superior nunca se mueven; cada pantalla igual.
 *  · Botón por defecto visible (anillo) que responde a Enter; Esc cancela.
 *  · Retroalimentación inmediata: estado "trabajando", avisos breves, guardado automático visible.
 *  · Perdón: lo destructivo pide confirmación y casi todo se anula en vez de borrarse.
