   PRISMA · articles.css
   Sección editorial "Articles": portada (/articles/), página de
   artículo (/articles/<slug>/) y el bloque de artículos de la página
   de autor (matiasortega.html). Las páginas se generan con
   scripts/generate.js desde data/articles.json.

   Criterio: periódico o journal contemporáneo, no blog. Manrope en
   todo; jerarquía por escala y peso, no por color; medida de lectura
   de 65 a 70ch; filetes de 1px (--line-on-ink) en lugar de tarjetas;
   cajas sin esquinas redondeadas; fechas y tiempo de lectura en
   etiqueta pequeña con tracking y números tabulares. Fondo --ink
   igual que el resto del sitio (los tokens "paper" ya son oscuros y
   no aportan contraste real al cuerpo de lectura).

   Prefijos: .art-* página de artículo · .ai-* portada y filas
   compartidas · .aa-* bloque de la página de autor.
