   THEME 4 — "Blueprint"
   Cool, professional, techy. A near-white/light-grey canvas
   (no warm cream) with the brand plum #443143 as the SINGLE
   accent — no orange/terracotta. Space Grotesk display + DM Sans
   body + DM Mono labels, a faint cool blueprint grid, sharp
   corners and square icon tiles.
   #443143 is headings ink, the lone accent, primary buttons and
   the deep CTA slab.
