The sidebar groups characters by language (GPT-SoVITS) or folder
(F5-TTS) in foldable groups; a character unfolds into its clips and a
click plays one through the studio row. Characters drag onto nodes from
the sidebar, a red dot marks characters that need a look, a search box
shows from six characters on, and files dropped on a GPT-SoVITS
character open "Add files" for it.
GPT-SoVITS settings move to a dialog opened from the sidebar footer,
which carries the reminder dot; "Import character" moves into the
studio toolbar. Canvas drag helpers move to audio_voice_drag.js so the
sidebar and the cards share them.
