The manuals gained executable catalog data, including examples for edge cases. Instead of describing a difficult input only in prose, a reader can open the example and inspect what the chart does.
The repository also recorded implementation evidence for its then-listed limitations and added a neutral theme family catalog. These records describe that source snapshot; they should not be read as a promise that every future input is supported.
Follow-up fixes kept volume examples spatially valid and aligned edge-case runtime contracts. When adapting an example, retain the documented data structure as well as the visible numbers.
