"""Channel UI layer (chip, progress bar and subtitles) for the videos rendered
in Blender. It is rendered with --transparent and composited over the 3D, so
the style comes from the same code as the Manim videos.
NAME=bolapeluda CHIP=Topología CHIPCOL=celeste manim --transparent ...
It also writes out/<name>_timeline.json, which the Blender script (to animate)
and build_video.py (to place the audio) read afterwards.
