Deploy, skill and result lines come from the operators' official voice slots; a newer line takes the channel over (stale callbacks of the replaced line no longer release it), and the result line is spoken by an operator of the player's own battle. Contributed by @Convey123.

Asset plan, manifest entry (audio.bgm.unite), audio.js and tests. Contributed by @Convey123.
The emote E2E suite accepts either the local-client extraction or the copies tools/fetch-assets.mjs downloads (public/assets/ui/emoticon), and checks the wheel's official cell sprite only when the local ui/battle art is present. Contributed by @Convey123.
