/* Numa Koudsie · data panel (scripts/datalog.js)
   A ledger of every number a simulation computes: numbered sections, one entry per quantity with a dotted
   leader to its value, small pictures of arrays, a recorder for one round, the three-way check.
   Uses the site tokens from sim.css; colours missing from older copies of sim.css have fallbacks. */
