   Concept: "The Register" — a Company Secretary's work is the art of
   keeping a company's record straight, on time, in order. The visual
   language borrows from statutory registers and ledgers: hairline rules,
   tab-indexed rows, mono filing codes, paper tones, one deep ink-blue,
   one restrained seal-red used only for what truly needs attention.
