-//! La lógica vive en `shuma-intent` (parser + grafo + macros) y
-//! `shuma-shell-render` (layout del lienzo); la ejecución real la hace
-//! `sandokan`. Esta v1 renderiza la estructura con datos de ejemplo —
-//! el cableado interactivo (typing en el prompt, F-keys) es el paso
-//! siguiente.
+//! El input no es un campo de texto tonto: `shuma-line` analiza la línea
+//! bash mientras se escribe —resaltado por token, autocompletado
+//! posicional, descomposición de los pipes—. Los monitores de la derecha
+//! grafican CPU y memoria con `shuma-sysmon`. Toda la lógica vive en
+//! crates agnósticos; este binario sólo es el frontend GPUI.
