// Zap tallies are asked of the relays on every boot, which takes seconds. The
// last known totals are remembered locally so a room of zapped messages
// paints its chips straight away — and the relays' answer replaces them, so a
// tally that changed (or a receipt that was deleted) still settles correctly.
//
// Run: bun tools/zap-tally-cache-test.js
