// Each script is a full petition lifecycle as SSE-shaped events with relative
// delays (seconds of simTime). main.js stamps feature.t at apply time so

// (the engine isn't running in mock — these were placed by hand against the
// genesis layout and do not collide with it or with each other).
//
// GENESIS_FEATURES mirrors the contract's genesis list verbatim — the fallback
// when web/mock/world.json (generated later by tools/gen_web.py) is absent.
