Const ES_INTERRUPTED - ES_INTERRUPTED indicates playback was cancelled (movement, teleport, another emote superseding it, explicit stop, or scene change).
ES_STARTED - ES_STARTED indicates the emote started playing. This is the zero value and is used for backward compatibility — entries written by older explorers (field absent) read as "started".
ES_FINISHED - ES_FINISHED indicates a non-looping emote completed naturally.
