Module theme 

Color palettes and visual styling for the Map widget.

Theme is a built-in set of named color palettes, each with a light and a dark variant (ColorMode); Theme::colors resolves a (Theme, ColorMode) pair to the actual ThemeColors palette. MapTheme is the customization point: implement it to install your own palette instead of one of the built-ins, the same way NodeTemplate and SegmentTemplate let you replace the built-in node/segment rendering. Style is the non-palette visual configuration (stroke widths, font, background) the widget paints with; it holds no color of its own – every color comes live from the active MapTheme, resolved fresh each frame, so nothing in Style can drift out of sync with the installed theme.
