   CK12 "Royal Proclamation" design system: tokens + shared primitives.
   One brand, three moods, chosen with data-mode on <html> or <body>:
     (default)            public website: midnight navy canvas, ivory text
     data-mode="utility"  staff tools: ivory surfaces, navy text (quiet luxury utility)
     data-mode="scanner"  door scanner: near-black, high contrast, no decoration
     data-mode="stage"    raffle on a projector: full cinematic brand
   Fonts (link per page):
     https://fonts.googleapis.com/css2?family=Cormorant+Garamond:ital,wght@0,500;0,600;0,700;1,500&family=Hanken+Grotesk:wght@400;500;600;700&display=swap
   Rules: gold is an accent (hairlines, small labels, focus, key numbers), never a flood.
   No gradients on UI surfaces, no glassmorphism, no glows, no heavy shadows.
   Never type the em dash character in this project.
