   ISSG — Integrated Smart Systems Group
   Design system, rebuilt from the Chakra UI theme the React site used.

   Every value here is the resolved Chakra token, not an approximation:
   spacing is n x 0.25rem, the gray ramp is Chakra's, the shadows are
   Chakra's, and the breakpoints are 30/48/62/80em. That is what keeps the
   rebuild looking like the original rather than merely similar.
