/*
 * Kairos4 console.
 *
 * The layout is kairos1's, ported: a 768px column sized for an iPad mini held
 * in portrait, a fixed bottom tab bar so the thumb never travels, monospace for
 * every number so columns line up without a table. What changed is what the
 * screen is FOR — kairos1's hero was equity, and this round's hero is fill
 * rate, because PnL at n=45 cannot resolve anything (PREREG §5.0).
 *
 * Dark only. This gets read on a phone at night, and a light theme would be a
 * second set of contrast decisions nobody will check.
