DEFAULT_FILL_TOKENS

Which palette token each fill *style* paints with.

The style names and the token names overlap without lining up, which is the easiest thing here to get wrong: semi paints the paper with barely a tint, solid paints the hue's pale tint (the semi token), and only fill paints the hue at full strength. Reading the token whose name matches the style makes every filled shape a step too saturated. Stated once, here, so a renderer and an exporter cannot disagree about it.

"paper" means the ramp's own solid surface colour, not a palette entry.

A swatch UI that previews the fill styles reads *tokens* by name instead (getColorValue(colors, "black", "semi")) — that is a UI decision about what to show, and it is deliberately not routed through this table.
