// The Russian read-back vocabulary lives in behavior_ru.json, not in Go source.
//
// It is data, not logic: a weekday name and a verb gloss are wording choices
// that change independently of anything the counter does, and having them as
// literals scattered through behavior.go meant every phrasing tweak was a code
// diff. go:embed keeps the single-binary deploy — the JSON is compiled in, so
// there is no file to install alongside mavend and no way for the two to drift.
//
// Parsed once at init. A malformed file is a panic, deliberately: it can only
// happen if the embedded asset is broken at build time, and a daemon that comes
// up with an empty vocabulary would answer with bare fact keys.
