/*
 * Civ13 wiki theme, layered over the stock mdBook theme.
 *
 * Shares the palette and type of civ13.github.io. Colour tokens override
 * mdBook's own variables for the default "navy" theme; the other built-in
 * themes keep their palettes but inherit the layout and typography rules.
 *
 * Contents
 *  1. Palette and base typography
 *  2. Menu bar and sidebar
 *  3. Content: headings, links, tables, code, images
 *  4. Page table of contents and subpage footer (built by nav-additions.js)
 *  5. Landing page components (src/index.md)
