              74 best-selling rugs across wool, jute, performance and indoor/outdoor — shown in
              one fixed order, identical for every visitor. A coastal blue lover and a
              pet-household shopper see the exact same grid.

              The same catalog, re-ranked per visitor vector — palette, material, room, durability,
              price tier and live behavior. Because the catalog is so diverse, every visitor gets a
              genuinely different first screen. On the PDP, recs shift from "more of the same" to
              rugs that actually pair across the home.
