   NovaRock Global Research — Design System
   Editorial / institutional research-desk aesthetic.
   Distinct from the NovaRock Advisory (burgundy) identity by design —
   this is a separate publication with its own visual voice: ink navy,
   warm paper, muted brass. Broadsheet layout, hairline rules, sharp
   corners, no card/SaaS chrome.
