   Memory City — strata sculpture view
   =============================================================================
   The sculpture is NOT a map: the vertical axis is time. Every driven
   street floats at the altitude of the moment it joined the city —
   ground level is founding day, the summit is the newest street.
   Undriven roads are absent.

   Encoding:
     - altitude = founding moment (blended time × founding order)
     - color    = active lens (recency / chapter / revisits)
     - shadow   = the street plan at ground level
