What’s new

🔧 Mejoras y correcciones

• Escáner de cromos más preciso: se han corregido varios casos en los que
la cámara identificaba mal el cromo (comparaba contra la colección
equivocada, o mostraba un número que no coincidía con lo impreso en la
carta).

• Los cromos de selecciones nacionales (Mundial) ahora se reconocen
correctamente aunque lleven el nombre completo del país en vez de una
sigla.
