Series colors in the fixed order (slot 1 to 3), never re-assigned when a series is hidden. Columns 22px thick with 4px rounded caps, a 2px surface gap between neighbors, values on the latest year only, legend present because there is more than one series.
Lines (3 series, end-labeled)
2px lines with 8px points ringed in white, the end value labeled, one y-axis only (two measures of different scale get two charts, never a second axis). Text stays in text colors; the colored mark beside it carries identity.
Stacked bars (5 categories, Other folded)
Segments separated by 2px of white, not by strokes. A sixth category folds into Other (Slate). Inline labels only where they fit; the rest is carried by the legend and the table view.
Donut with a hero number
The one circle the layout gets. At most five segments, the one the story is about in Yellow, the hero number in the middle, the rest in the legend with values. Never a 3D or exploded pie.

One number, a label, a one-line context. PBS Blue for the figure, Navy label, muted context, on Cloud. Three across at most; no chart behind them.

Always with an icon or word; never reused as a series in the same chart.
Defined once as chart-* tokens. Charts sit on white; on a Navy slide use one series (Teal or Yellow) with white labels, because the accents are too light to stack as a series set on dark.
