"""Schema 4: split animated symbol palettes from the authoring palette.
|
||
|
|
|
||
|
|
Before schema 4 a symbol's ``:palette`` leaf value was always a channel. It now
|
||
|
|
names the static palette used when that symbol is the viewed root, while the
|
||
|
|
old channel is retained as ``:palette-channel`` compatibility data. New edits
|
||
|
|
use a real lane symbol referenced by ``:palette-track``.
