   Arletex Design System v3.5
   -------------------------------------------------------------
   Unifica los antiguos cholula-cuadros.css y cholula-tapetes.css.
   Tokens --ax-* heredados de landing-producto.css (cargar antes).
   El riel y las flechas de los carruseles viven en landing-producto.css
   (§26 AX-SCROLLER).

   PARTE A · .chq-*  (cholula · cuadros)
     Sección "cuadros sublimados"
     Registro:  @gallery (la imagen manda)
     Apertura:  Dossier minimizado (eyebrow stamp)
     Marco:     Bleed-edge (fondo pleno full-width, sin marco)
     Hover:     lift-orange con scale 1.02 (excepción canónica de
                @gallery) · press-chunky y ghost-fill en las CTAs
     Va entre el banner-llegada (ink) y el cross-sell (white): el
     fondo paper corta la cadena de bloques oscuros.

   PARTE B · .cht-*  (cholula · tapetes)
     Bloque "tapetes y fundas de fiesta": tres sections encadenadas,
     cada una con su propio registro para que el bloque no se lea
     como tres cajas iguales:

     §B2 .cht--lead  @news      · RunInHeadline · Double-rule · white
                                · hover rule-draw (links de prosa)
     §B3 .cht--mats  @fanzine   · NumberProtagonist · Brick-stack · ink
                                · hover ghost-fill (cards de intención)
     §B4 .cht--arch  @almanac   · IndexRow · Index-tab · paper
                                · hover side-shift (pasos de medición)

     Viven DENTRO del tab "Descripción" (dentro de un .container de
     Bootstrap), así que no son bandas full-bleed: son tres bloques
     apilados con aire entre ellos, al ritmo de las .tarjeta-beneficio
     vecinas. Cadena de fondos: white → ink → paper, nunca dos ink
     seguidos y el ink queda aislado entre dos bloques claros.
     §B7 añade las fichas del carrusel de usos (tab "Usos").
