bynk.locale — the bundle-free render/renderArg helpers and the message/withText/withWhole/withNum/withMoment builder API (slice 1: render formats code plus a deterministic sorted-by-key rendering of params; no lookup, no locale-dependent behaviour). uses bynk.locale.types for the types its own signatures name.
