   Sinclair & Blackstone — Global Stylesheet
   Design system: quiet, paper-and-ink editorial. Warm bond-paper surfaces,
   near-black text, and a single deep oxblood accent used sparingly for
   interactive elements only (buttons, links, the current page, required
   fields). No illustration, no decorative watermarks, no case-file
   theatrics — the type and the grid do the work.
