/* assets/css/panel.css
 * Sistema de diseño del PANEL (todo lo que hay tras iniciar sesión).
 *
 * Depende de assets/css/landing.css, que aporta los tokens --mg-* y las
 * primitivas compartidas (.mg-btn, .mg-label, .mg-shell). Aquí sólo van los
 * componentes propios del panel: chrome, tarjetas, tablas, formularios.
 *
 * Todo lleva prefijo mg- a propósito: assets/css/style.css define 54 reglas
 * !important sobre .card, .badge, .text-muted, .bg-white y .lead. Usar clases
 * propias evita la guerra de especificidad.
