         (rules, italic emphasis, masthead dots, CTA plates).
       · Coral / Clay / Brass / Slate-accent / Teal are the CRAFT palette —
         used inside individual small graphics (pull-quotes, key-takeaways,
         charts, tags) to give each piece mood without fragmenting identity.
     Never let a craft color take Citron's role; never put two craft
     colors in the same composition (one per graphic). */
