   Concept: "contour lines" – alpine topography as a quiet metaphor for
   mapping and controlling a risk landscape. Night-blue surfaces, glacier
   blue for the brand, amber reserved for the product AI Prompt Shield,
   three semantic colours for its decisions (allow / modify / block).
   No external resources, no inline styles (strict CSP).
