/* Quadrille HOUSE — multi-brand editorial lookbook over the Quadrille family of lines,
   served under Designer Wallcoverings house chrome at quadrille.designerwallcoverings.com.

   - House brand = Designer Wallcoverings (corner wordmark, nav, footer).
   - Featured = the Quadrille HOUSE: China Seas, Quadrille, Alan Campbell, Home Couture,
     Charles Burger, Lulu DK, Cloth & Paper, Suncloth, Plains, Grasscloth (REAL brand names).
   - brand/line FILTER switches between lines.
   - Two CTA modes: live (China Seas → real DW product link) | quote (held net-new → memo/quote).
   - NO prices anywhere on the landing.
   - Lookbook section surfaces 32 harvested PDFs + room imagery.
