+`FsCodec.Box.Codec` is a drop-in-equivalent for `FsCodec.(Newtonsoft|SystemText)Json.Codec` with equivalent `.Create` overloads that encode as `ITimelineEvent<obj>` (as opposed to `ITimelineEvent<byte[]>` / `ITimelineEvent<JsonElement>`).
 
 This is useful when storing events in a `MemoryStore` as it allows one to take the perf cost and ancillary yak shaving induced by round-tripping arbitrary event payloads to the concrete serialization format out of the picture when writing property based unit and integration tests.
