/* A&J Sewer Service — redesign v3
   World: Chicago trade-badge heritage. Union-hall poster and badge
   vernacular rendered at a premium register: crest, civic stripe bands,
   the brand's diamond doing the flag star's job, one blue carried at
   page scale. Type: Bricolage Grotesque display over Public Sans.
   Disciplines raised from the dealt challengers: strict band rhythm,
   one icon grammar (the diamond only), a fixed 4-step blue ladder,
   ghost states as outline diamonds, one type-only section, one dated
   line through About. */
