 * MedSuite — public/assets/css/nav.css
 * Copiado de Bizsuite @98ceec0 (public/assets/css/nav.css).
 * -----------------------------------------------------------------------------
 * El encabezado de la aplicación y el menú lateral.
 *
 * Es la primera de las capas de MedSuite (docs/PLAN_DESARROLLO.md §4,
 * docs/ARQUITECTURA.md §1.1): theme → base → components → nav → clinica →
 * hoja del módulo. Lo de abajo es la hoja de Bizsuite SIN CAMBIOS, a propósito:
 * así se compara línea por línea con la de origen y se puede volver a copiar.
 * Lo que MedSuite corrige (contraste AA de --muted, --ok, --warn, --error e
 * --idle; foco visible en los campos) y la capa médica van en clinica.css, que
 * se carga después. No tiene url() ni @import: nada se pide fuera del sitio.
