   Nexora Digital — Design tokens
   Palette:  ink (near-navy) / paper (cool white) / primary blue /
             amber accent used sparingly / slate text
   Type:     Space Grotesk (display) + Inter (body) + IBM Plex Mono
             (eyebrows, stat numbers, labels — a "digital" signature)
   Signature: bracket-corner frame motif on hero image, portfolio
             thumbnails, and cards — nods to "select / focus" in
             creative software, tying back to "Digital" in the name.
