Overview ¶
Package theme holds the visual tokens a chart is drawn with: colours, fonts, sizes and spacings.
A theme is plain data. It is resolved once, before lowering, and every decision that is "how should this look" reads from it rather than hardcoding a value — which is what makes a second theme a data change instead of a code change.
