  "_comment": "A theme is a palette and a typeface, nothing more. Every slide type draws from these names, so adding one here restyles the whole deck with no change to any slide builder. tint/tint_alt are the two card fills a comparison uses, and accent_alt is the second hue: the edge of the second card and of a callout. Before these existed both were hardcoded blue and amber, so those cards stayed the same colour under every theme. Colours are hex without a leading #, the form python-pptx wants.",
