//! Galería de los iconos de marca de todas las apps de gioser.
//!
//! Pinta los 29 [`AppIcon`] en una grilla, cada uno en su color de marca
//! con su nombre debajo. Sirve para eyeballear de un vistazo que el set
//! es coherente (mismo peso de trazo, mismo aire) y que cada glifo es
//! reconocible.
