   Design direction:
   ─ Formal, minimalist, corporate with subtle magazine warmth
   ─ #1e3a8a is the dominant identity colour throughout
   ─ Light theme: navy-tinted backgrounds, NOT white
   ─ Dark theme: deep navy, high contrast
   ─ Fonts: Lato (body) + Playfair Display (display/headings)
   ─ Base 18px, generous line-heights
   ─ 90-degree corners everywhere except input fields
