mnemo-rs 1.7.0

//! Rendu Ratatui de la TUI, style « ops dashboard ».
//!
//! Disposition verticale :
//! - **barre de commande** (haut) : badges identité (mnemo + version + projet +
//!   branche + total), barre de recherche, puces de filtres actifs ;
//! - **synthèse / KPI** : total, visibles, succès, échecs, taux d'échec,
//!   projets, shell dominant (masquée sur terminal court) ;
//! - **corps** : liste des commandes (gauche) et panneau de détails sectionné
//!   (droite, masqué sur terminal étroit) ;
//! - **pied** : raccourcis essentiels et message de statut.
//!
//! Toutes les couleurs passent par [`crate::tui::theme`] ; le formatage des
//! chaînes par [`crate::tui::format`]. Le rendu est responsive et ne panique
//! jamais, y compris en dimensions réduites.
