Guide map design from scratch using established cartographic principles (color, projection, type, symbols, visual hierarchy, layout). Use this whenever the user is making or planning a map or map figure and needs design decisions — choosing a color scheme, picking a projection, deciding class breaks, setting up labels, or laying out a figure for a paper, poster, slide, or web. Trigger it even when the user just says "make a map of X," "what colors for this map," "how should I map this data," or asks for cartographic feedback, and even when they don't say the word "cartography." Especially relevant for publication-quality figures where grayscale-robustness and colorblind-safety matter.
