   Arletex Design System v3.5 — Rollos De Tela (/telas/rollos-de-tela)
   Hoja editorial por página. Prefijo de clase y de token: rt- / --rt-*.
   Tokens locales con fallback a --ax-* global y, si no, a hex del sistema.
   ─────────────────────────────────────────────────────────────────────────
   TEMA: la ficha del fabricante. Rollos = mayoreo, gramajes, metrajes,
   anchos, escalas de precio. Se apoya en registros Técnico y Almanaque
   (telemetría mono, spec sheets, banda de datos) sin abandonar la marca:
   orange/ink/paper. El purple es la señal secundaria de "mayoreo/escala".
   Se conserva TODO el SEO del original (meta, schema, headings, keywords en
   <strong>, enlaces internos e imágenes). ≥55% blanco; ink como puntuación.
