/* ============================================================================
   Tesela — Portada de la galería: pared de teselas
   Una tesela por experimento (212), en módulo cuadrado estricto. El color de cada pieza lo pone su carpeta,
   mate y desaturado; el dorado mate se reserva para los favoritos y los filetes finos.
   Los colores base salen de los tokens de la biblioteca, así que el tema, el preset y el acento se respetan.
