mu915275-cmd/dsh-boot-animation

Plays an intro full-frame on a new conversation, or every time you open the one you pinned. Four clips ship inside the plugin itself, embedded in code with no separate video files, and an in-app library switches between them, previews the choice, and accepts your own clip. The picker has two independent sections, so the intro animation and the workspace wallpaper are picked separately; the wallpaper can be a still or a looping tail of the last N seconds, with independent transparency for the picture and the sidebar plus three blur levels. The sidebar and the workspace also get a text colour each, for when the picture is at full strength and the theme own text no longer reads.
