// In its own words

How it explains its own design

Original text, in Spanish.

Tesis: una revista impresa que se comporta como un instrumento de medida. El papel cálido, la tinta y el bermellón de señal conviven con una retícula visible, marcas de registro y microtipografía monoespaciada. La serif de display (Instrument Serif) pone la voz humana; Newsreader sostiene la lectura; JetBrains Mono anota la maquinaria.

Todas las imágenes son instrumentos generados de forma determinista en SVG y canvas a partir del slug de cada pieza: campos de puntos que se vacían, interferencias, anillos de atención y espectros. Nada de fotografía de stock ni degradados decorativos.
