/* Who Could Have Known?
   Two sources: the Data Power cover (white field, viridis, light letterspaced serif) and
   Debord & Jorn's "The Naked City" (cut-out map fragments joined by arrows).
   Viridis encodes time: older is purple, newer is yellow. Red is reserved for détournement marks and misses.
   Fonts are self-hosted (OFL); nothing loads from third parties. */
