import {AUDIO_EXTENSIONS} from '@fuzdev/zzz/diskfile_content_kind.js'; Extensions viewed as audio. Each is one the backend serves with a media
type (twin of media_content_type in zzz_server's file_bytes.rs), so
an <audio> element can play it from the byte route. webm is here
because that's what a recording is; a .webm holding video plays as its
audio track.
