   Shirleigh Consulting Management — Stylesheet
   Design language: heritage advisory house. The name itself reads like an
   old family firm, so the system leans classical rather than technical or
   civic: mahogany and brass, a monogram seal, engraved double-rule
   borders, and Roman numerals for sequence — the register of a trusted,
   long-standing advisory practice rather than a startup consultancy.
   Palette: deep walnut brown, brass/gold, muted burgundy, warm ivory.
   Type: Cormorant Garamond (elegant display serif) + Karla (body/UI).
